  • Publication number: 20240110068
    Abstract: A thin oil film having parylene irregular dendritic-like columns extending from one side to another exhibits hydrophobic properties that can be used as a corrosion resistant coating or water-repellant, biofouling resistant surface. This parylene-in-oil layer can be paired with an adjacent layer of solid parylene that it overlays or underlays. The solid parylene cross polymerizes with the parylene dendrites, keeping them in place as well as the oil film. The parylene dendrites are fabricated by chemical vapor deposition (CVD) of parylene over the oil layer, the dendrites self-forming from the bottom to the top. Continued CVD over the dendrites can produce a top layer of solid parylene. Etching the solid parylene away can result in a water repellant, anti-biofouling surface.

  • Patent number: 11931184
    Abstract: A hand-held device, such as a remote control, is provided for operation of a consumer appliance and is equipped with one or more biometric sensors to capture and report on the health condition of a user of the hand-held device. The data captured by such a hand-held device may be evaluated locally in the hand-held device itself or may be conveyed to a target consumer appliance either for local evaluation by that consumer appliance or for onward transmission to a central off-site monitoring service.

  • Patent number: 11925717
    Abstract: A photosensitizer formulation can be disposed on or in a mesh; net; netting; screen; curtain of strands, fibers, or monofilaments; substrate, personal protective gear, mask, or any other suitable object. The photosensitizer formulation, when in contact with molecular oxygen and activated by light or ultrasound, produces microbicidal singlet oxygen. A variety of different arrangements and applications are described. For example, an air flow device may also be included to generate a flow of air through or over the photosensitizer formulation. A fluorescent formulation may be included to monitor photobleaching. The photosensitizer formulation may be disposed in a concentration gradient to generate antigenic particles by damaging or destroying microbes.

  • Patent number: 10916683
    Abstract: A light emitting device includes a vertical via through the P-type semiconductor layer and the active layer. Using a vertical via reduces quantum well damage, allows shortening of P-N spacing, and allows increased reflective area. A dielectric structure is formed in the via to provide a sloped wall that extends to an upper surface of the device. Another dielectric layer covers the upper surface and the sloped wall, and provides select contacts to the semiconductor layers. A metal layer is subsequently applied. Because the dielectric layers provide a continuous slope from the surface of the device, the metal layer does not include a vertical drop. Because the active layer does not extend into the via, the contact to the N-type semiconductor layer may be situated closer to the wall of the via, increasing the area available for a reflective layer.

  • Patent number: 10712759
    Abstract: Power supply rejection (PSR) peaking in Low Dropout (LDO) voltage regulators can lead to reduced bandwidth and efficiency. The present invention is directed to a new design method by combining power transmission lines (PTL) with LDOs for enhancing its bandwidth and efficiency. This approach is applicable for LDOs regulating high speed I/O drivers. The PTL combined with decoupling capacitors on the package or board are used to mitigate the PSR peaking. This methodology is demonstrated using printed circuit board test vehicles with off-the-shelf components. When compared to conventional approaches, the PTL solution showed ˜80% lower power supply noise.
