Abstract: A femoral neck trochanteric nail makes use of a dual, lag-screw/anti-rotation screw assembly to provide two, spaced fixation points locatable across a femoral neck in conjunction with a corresponding hip procedure. The anti-rotation screw may be advanced through a bore in the lag screw after the lag screw has been suitably fixed to a trochanteric nail received at an intramedullary location. The lag screw and anti-rotation screw construct may be oriented in different positions to have corresponding fixation points at different angular locations after fixation.

Abstract: Methods for making a B-stage thiol-cured urethane acrylate elastomeric film are provided. At least a urethane acrylate oligomer, a multifunctional thiol, and a base catalyst are combined to form a thiol terminated B-stage elastomer. The thiol terminated B-stage elastomer is exposed to an ultraviolet photoinitiator in the presence of an allyl ether terminated urethane to form the B-stage thiol-cured urethane acrylate elastomeric film. In some embodiments the B-stage thiol-cured urethane acrylate elastomeric film is used for a soft actuator application such as a fluidic elastomer actuator application or an electrostatic zipping actuator application.

Abstract: A low cost, handheld device, according to the present invention, enables surgeons to perform cataract surgery manually through a small incision in order to minimize surgically induced astigmatism and reduce recovery time.

The device has been designed for use in emerging markets, is less-invasive than current techniques, meets the cost and time constraints of high volume eye care systems, fits within the existing training and clinical paradigms, is comfortable and allows for dexterity of movement in the hands of a surgeon, and is able to fragment all grades of cataract, including mature cataracts, meeting the needs of the entire patient population.

Abstract: A method includes separately exposing selected portions of a first rigid substrate and a second rigid substrate to laser radiation, selectively etching the exposed portions of the first rigid substrate and the second rigid substrate using a chemical etchant and bonding the first rigid substrate to the second rigid substrate along a common interface to form a fluidic valve. The fluidic valve may be coupled to a fluidic haptics device, for example, which may be integrated into an artificial reality system.

The monolithic gate substrate may include a gate chamber and a flexible membrane located adjacent to the gate chamber. The channel substrate may include a source channel and a drain channel that are in fluid communication with the flexible membrane on an opposite side of the flexible membrane from the gate chamber. Various other related devices, systems, and methods are also disclosed.

Abstract: A Group-III nitride light emitting device that utilizes scattering of hot carriers generated by Auger recombination from an externally electrically-driven, relatively narrow band gap carrier generation region into a relatively wide band gap carrier recombination region, such that the relatively wide band gap carrier recombination region of the Group-III nitride light emitting device is internally electrically injected by the hot carriers generated in the externally electrically-injected relatively narrow band gap carrier generation region. The device is used for generation of incoherent light (a light-emitting diode) or coherent light (a laser diode).

Abstract: A processing device executing a wide area network (WAN) accessible service receive an encrypted digital image comprising a firmware update for an embedded system of a device having a specific device serial number (DSN). The processing device additionally receives device related information from a computing device, wherein the device related information comprises the DSN of the device comprising the embedded system and a version number of a current firmware component installed on the embedded system. The processing device determines, using the device related information, that the encrypted digital image for the device is available. The processing device then provides the encrypted digital image to the computing device for use by the computing device to update a firmware version of the embedded system.

Abstract: An example heating, ventilation, and air conditioning (HVAC) vent includes a front surface, an RF module, and an antenna coupled to the RF module. The front surface is configured to direct air flowing through the HVAC vent into a room, and includes an antenna opening. The RF module is configured to wirelessly transmit or wirelessly receive a communication signal. A portion of the antenna protrudes through the antenna opening and beyond a plane of the front surface.

Abstract: Improvements in stringed instrument playing tool is disclosed. The guitar pick stick has curved and flat surfaces that allows the tool to strike one or multiple strings using the curved surface or to strike multiple strings using the side of the curved surface to reach end strings or all of the strings on the instrument. The end can be pointed, fanned or have other shapes that further be used to pick or strum individual strings. Using the different areas can produce different sounds and in addition, striking the strings at different locations along the length of the strings can produce different tonal effects. A raised area can exist in the center or off-center of the guitar pick stick and allows the user to rub the raised area of the guitar pick stick across one or a variety of strings to provide a different acoustical sound.

Abstract: A hardware module for an embedded system comprises a network adapter, a memory and a processing device. The memory stores a shared key and a key identifier (ID) associated with the shared key. The processing device is to connect to a local area network (LAN) using the network adapter. The processing device is further to receive a first notification from a computing device that is also connected to the LAN and determine whether the computing device has access to a copy of the shared key based on the key identifier (ID). Responsive to determining that the computing device has access to the copy of the shared key, the processing device is to use the shared key to generate a session key for a session with the computing device. The processing device may then encrypt communications to the computing device using the session key.
