A resolver is a type of rotary electrical transformer used for measuring degrees of rotation. It is considered an analog device, and has digital counterparts such as the digital resolver, rotary (or pulse) encoder.
The most common type of resolver is the brushless transmitter resolver (other types are described at the end). On the outside, this type of resolver may look like a small electrical motor having a stator and rotor. On the inside, the configuration of the wire windings makes it different. The stator portion of the resolver houses three windings: an exciter winding and two two-phase windings (usually labeled "x" and "y") (case of a brushless resolver). The exciter winding is located on the top; it is a coil of a turning (rotary) transformer. This rotary transformer induces current in the rotor without wires or brushes to provide a direct electrical connection. The two other windings are on the bottom, wound on a lamination. They are configured at 90 degrees from each other. The rotor houses a coil, which is the secondary winding of the turning transformer, and a separate primary winding in a lamination, exciting the two two-phase windings on the stator.
The primary winding of the transformer, fixed to the stator, is excited by a sinusoidal electric current, which by electromagnetic induction induces current in the rotor. As these windings are arranged on the axis of the resolver, the same current is induced no matter what its position. This current then flows through the other winding on the rotor, in turn inducing current in its secondary windings, the two-phase windings back on the stator. The two two-phase windings, fixed at right (90) angles to each other on the stator, produce a sine and cosine feedback current. The relative magnitudes of the two-phase voltages are measured and used to determine the angle of the rotor relative to the stator. Upon one full revolution, the feedback signals repeat their waveforms. This device may also appear in non-brushless type, i.e., only consisting in two lamination stacks, rotor and stator.
Resolvers with four output leads are general sine/cosine computational devices. When used with electronic driver amplifiers and feedback windings tightly coupled to the input windings, their accuracy is enhanced, and they can be cascaded ("resolver chains") to compute functions with several terms, perhaps of several angles, such as gun (position) orders corrected for ship's roll and pitch.
For the position evaluation, resolver-to-digital converters are commonly used. They convert the sine and cosine signal to a binary signal (10 to 16 bits wide) that can more easily be used by the controller.
Multipole resolvers may also be used for monitoring multipole electrical motors. This device can be used in any application in which the exact rotation of an object relative to another object is needed, such as in a rotary antenna platform or a robot. In practice, the resolver is usually directly mounted to an electric motor. The resolver feedback signals are usually monitored for multiple revolutions by another device. This allows for geared reduction of assemblies being rotated and improved accuracy from the resolver system.
You can think of each field in a GraphQL query as a function or method of the previous type which returns the next type. In fact, this is exactly how GraphQL works. Each field on each type is backed by a function called the resolver which is provided by the GraphQL server developer. When a field is executed, the corresponding resolver is called to produce the next value.
In this example, our Query type provides a field called human which accepts the argument id. The resolver function for this field likely accesses a database and then constructs and returns a Human object.
Notice that while the resolver function needs to be aware of Promises, the GraphQL query does not. It simply expects the human field to return something which it can then ask the name of. During execution, GraphQL will wait for Promises, Futures, and Tasks to complete before continuing and will do so with optimal concurrency.
Resolving the name in this case is very straight-forward. The name resolver function is called and the obj argument is the new Human object returned from the previous field. In this case, we expect that Human object to have a name property which we can read and return directly.
In fact, many GraphQL libraries will let you omit resolvers this simple and will just assume that if a resolver isn't provided for a field, that a property of the same name should be read and returned.
This is an example of scalar coercion. The type system knows what to expect and will convert the values returned by a resolver function into something that upholds the API contract. In this case, there may be an Enum defined on our server which uses numbers like 4, 5, and 6 internally, but represents them as Enum values in the GraphQL type system.
The resolver for this field is not just returning a Promise, it's returning a list of Promises. The Human object had a list of ids of the Starships they piloted, but we need to go load all of those ids to get real Starship objects.
Replying so i can mark as solution: TL;DR: Traefik 2.x does not indicate when the acme.json file could be opened but contains invalid data. In this case, the certificate resolver silently fails resulting in the cryptic "router uses non-existant...
I wanted to attach a second lambda resolver for a different GraphQL query. I added a new lambda as a data source, but when I click Attach in the schema next to the query, I am forwarded to the page for creating a pipeline resolver and there is no way to choose a lambda resolver instead.
Now, even when I just create a new copy of the previous AppSync API with one query and want to attach a lambda resolver to that single query, there is no way to attach a lambda resolver any more. Though it was possible earlier this week. And I can see on old APIs that they are still using lambda resolvers.
When the pipeline page opens you select the "Actions" dropdown menu, and then you can choose the "Update runtime" option. Under resolver type you can then choose a Unit type resolver which you are probably looking for.
I verified this by forcing my PC to use 1.1.1.1 and it connected right away, but once I went back to using Pihole, it failed while pihole was showing the query coming in and being forwarded to the resolver on PFsense.
First the problem: I have a login mutation. It returns the user object on successful login. Originally the user object simply contained built in types (string, boolean, ect) so no extra resolvers aside from the login resolver where needed. However I then added another field called workspaces to the user which has its own resolver.
I've noticed on a few of the Pi-hole discussion and support channels that people in general seem to be completely unaware that it's dangerous to have a DNS resolver open to the world on a public server, and many have done so because of the ease of setting up and using Pi-hole.
The preferred series for rugged and accurate rotary positioning. These resolvers have been the standard rotary position method in packaging, primary metals manufacturing, stamping, automotive, tire and rubber, paper mills and mining.
The DNS Resolver in pfSense software utilizes unbound, which is avalidating, recursive, caching DNS resolver that supports DNSSEC, DNS over TLS,and a wide variety of options. It can act in either a DNS resolver or forwarderrole.
Data sources and resolvers are how AWS AppSync translates GraphQL requests and fetches information from your AWS resources. AWS AppSync has support for automatic provisioning and connections with certain data source types. AWS AppSync supports AWS Lambda, Amazon DynamoDB, relational databases (Amazon Aurora Serverless), Amazon OpenSearch Service, and HTTP endpoints as data sources. You can use a GraphQL API with your existing AWS resources or build data sources and resolvers. This section takes you through this process in a series of tutorials for better understanding how the details work and tuning options.
AWS AppSync uses mapping templates written in Apache Velocity Template Language (VTL) for resolvers. For more information about using mapping templates, see the Resolver mapping template reference. More information about working with VTL is available in the Resolver mapping template programming guide.
AWS AppSync supports the automatic provisioning of DynamoDB tables from a GraphQL schema as described in Provision from schema (optional) and Launch a sample schema. You can also import from an existing DynamoDB table which will create schema and connect resolvers. This is outlined in Import from Amazon DynamoDB (optional).
A resolver is an electromagnetic transducer that can be used in a wide variety of position and velocity feedback applications which includes light duty/servo, light industrial or heavy duty applications. Resolvers, known as motor resolvers, are commonly used in servo motor feedback applications due to their good performance in high temperature environments.
Because the resolver is an analog device and the electrical outputs are continuous through one complete mechanical revolution, the theoretical resolution of a single speed resolver is infinite. Because of its simple transformer design and lack of any on board electronics, the resolver is a much more rugged device than most any other feedback device and is the best choice for those applications where reliable performance is required in those high temperature, high shock and vibration, radiation and contamination environments which makes the resolver the sensible design alternative for shaft angle encoding.
The resolver is a special type of rotary transformer that consists of a cylindrical rotor and stator. Both the rotor and the stator are manufactured with multi-slot laminations and two sets of windings. The windings are normally designed and distributed in the slotted lamination with either a constant pitch-variable turn or variable pitch-variable turn pattern. In either case, the winding distribution is in a sinusoidal pattern.
