Soft Touch Video Conversion

[Dawnell Sechler]

Not compatible for use as a replacement for new Sidekicks and WH-200s that already have 5 lobe soft-touch knobs. These knobs have a different thread pitch. If you need a replacement knob for these products or any other part, please contact us.

This kit allows you to replace the quick-release clamp on the Sidemount Wimberley Head (WH-200-S) with the swinging arm and platform of the full gimbal Wimberley Head (WH-200). The Head can easily be converted back to the Sidemount version when desired by reversing the steps.

The procedure is simple, and the only tool required is an included 5/32 hex key

I have a 14'short wall that I am putting LQs in. I would like for the walls to have some kind of leather look or soft touch to them. I have seen some vinyls that look like leather, but what would you use to secure it to the walls? Thanks for your input.

No, unfortunately, we have not found anything either. I have found the fabric...but not prefoamed on the back. We are at our wits end. If anyone figures out where to find it, PLEASE let me know too. Thank you.

Hi everyone... You can order the vinyl from Larry Dennis Company. # 1-817-222-9700. It is glued to the walls with a spay on adhesive. Try Stay Put. It can be ordered from a RV supply store. It is made by AP Products. It sales for around $18.00 a can. It's Polystyrene Foam adhesive. If you use the wrong glue it will melt the foam backing.

Soft touch polyester film, also called soft touch PET film, is a plastic film that has been treated so that it feels soft and smooth to the touch. Soft touch PET film has tactile, physical, mechanical, optical, thermal, electrical and chemical properties that make it very well suited for many specialized applications.

Touch and itch sensations are crucial for evoking defensive and emotional responses, and light tactile touch may induce unpleasant itch sensations (mechanical itch or alloknesis). The neural substrate for touch-to-itch conversion in the spinal cord remains elusive. We report that spinal interneurons expressing Tachykinin 2-Cre (Tac2Cre) receive direct Aβ low threshold mechanoreceptor (LTMR) input and form monosynaptic connections with GRPR neurons. Ablation or inhibition markedly reduces mechanical but not acute chemical itch nor noxious touch information. Chemogenetic inhibition of Tac2Cre neurons also displays pronounced deficit in chronic dry skin itch, a type of chemical itch in mice. Consistently, ablation of gastrin-releasing peptide receptor (GRPR) neurons, which are essential for transmitting chemical itch, also abolishes mechanical itch. Together, these results suggest that innocuous touch and chemical itch information converge on GRPR neurons and thus map an exquisite spinal circuitry hard-wired for converting innocuous touch to irritating itch.

Itch invariably provokes the urge to scratch, while bodily responses to touch are remarkably diverse and influenced by multifaceted factors, such as the nature and intensity of tactile stimuli as well as the areas stimulated. Both touch and itch can elicit a defensive response, and are important for animal survival and welfare1,2,3,4. While itch and touch are encoded through distinct neuronal pathways from the periphery to the brain5,6,7,8,9, one fascinating observation is that a nonitchy stimulus such as a light touch may evoke an unpleasant itch sensation on the hairy skin10,11,12, known as mechanical itch or alloknesis. Mechanical itch presumably informs animals of external environmental irritants (e.g., insects and wool)13,14. Physical contact with textile fibers such as wool or cotton swabs from the seemingly normal skin area neighboring the itchy skin often evokes itching sensation15. Because alloknesis could be intolerable under pathological itch conditions, it could be a presenting problem for patients with chronic itch, including atopic dermatitis, dry skin itch, and urticaria3,16,17,18,19,20. One plausible mechanism is the excitation of the spinal interneurons, which receive input from low threshold mechanoreceptors (LTMRs)11,13,21.

The spinal cord interneurons expressing Tachykinin 2 (Tac2), which encodes neuropeptide neurokinin B (NKB)32, are exclusively located in the LTMR recipient-zone (RZ)7,33. In this study, we aimed to test the hypothesis that Tac2 neurons are required for mediating mechanical itch. Our study reveals that Tac2 neurons receive Aβ LTMR inputs and are required for mechanical, but not chemical, itch under normal physiological condition. However, Tac2 neurons located in lamina IIi are activated to participate in chemical and mechanical itch only under pathological itch conditions. Contrary to previous studies, we find that GRPR neurons are essential for mediating mechanical itch and function downstream of Tac2 neurons to convert innocuous touch to irritating itch.

The loss of mechanical itch in mice treated with BB-sap suggests a crucial role of GRPR neurons in mechanical itch transmission. Anatomically, rabies virus circuit tracing that revealed monosynaptic connections between Tac2 neurons and GRPR neurons supports this conclusion. The discrepancies between the present and previous studies21,26,27 can be ascribed to several methodological differences (see Supplementary Table 1). First, poking the nape of nave mice ten times instead of five is advantageous (Supplementary Table 1), because it permits comparable evaluation of mechanical itch between nave mice and mice treated with BB-sap using the same approach (nape). Second, given that application of von Frey to the nape evokes only a few scratching bouts (

The present finding is further consistent with the observation of augmented alloknesis in a mouse model of dry skin itch21,26,27,31,42. One notable difference between human and mouse chronic itch models is that the latter is a type of chemical itch in nature, for the development and maintenance of scratching behavior are contingent on periodic application of chemicals to the nape as well as enhanced expression of GRP in DRGs and GRPR in the spinal cord6,49,50. Therefore, the fact that enhanced alloknesis in pathological dry skin itch in mice underscores that mechanical and chemical itch are inherently coupled, with the former depending on the latter. Moreover, since the perception and motor output of acute chemical itch, dry skin itch and mechanical itch are identical, it is economic for spinal GRPR neurons to convert touch to itch rather than using a separate neural pathway for mechanical itch transmission. Given that histaminergic itch transmitted via NMB and NMBR neurons is also converged on GRPR neurons23, GRPR neurons are the last interneuron station in the spinal cord for integrating and transmitting mechanical itch from the periphery to the brain9,51.

Viking Plastics provides unique solutions for converting a metal component to plastic. The demand for conversions is constantly increasing as more and more companies seek ways to reduce weight, improve efficiency, and save on cost. Viking offers a variety of plastics, including ABS, PC, PC/ABS, PPS, PEI, and various grades of Nylon and Glass Filled Nylons.

The process of metal to plastic conversion starts with an assessment of the moldability of the component, followed by feedback on design changes for manufacturability (DFM) via injection molding. Once the design is updated, a Finite Element Analysis (FEA) is performed to understand loading, stresses, and base material strength requirements. Armed with this information, the Viking Plastics team works with material suppliers to locate suitable resins with the proper characteristics for the application. This includes an analysis of material strength, environmental exposure needs, chemical resistance needs, etc.

With a base design and material selected, the FEA is re-run to determine confidence and safety factors. Once these are established, flow analysis software is utilized to optimize gate location and size. A warpage analysis provides feedback on projected results from the molding process and offers guidance on the location of water lines and potential for part model tweaks to compensate for shrink and warp. Typically, customers then order a prototype mold/parts for confirmation and testing, followed by production tooling and quantities, to meet demand.

Most of us will encounter soft touch overmolding at some point in our lives, often without even recognizing it. Though hard plastics are useful for their strength and durability, products sometimes need a little bit softer touch to ensure product users are comfortable.

Benefits to this process include reduced cycle times and improved part quality and performance. Because these products require less manufacturing steps, manufacturing costs can often be reduced as well. For users, the benefits are plentiful, from enjoying a softer grip surface to building in additional flexibility for otherwise rigid parts. Product designers likewise have a lot more flexibility for product design, functionality, and aesthetics.

Critical considerations include wall thickness uniformity and proper material selection. Special care should also be taken to ensure any transitions between wall thickness are gradual enough that the flow of resin is not restricted. It is advisable to select a knowledgeable engineering partner to assist you in the design of your overmolded products to ensure designs will produce parts with proper adhesion.
