  • Patent number: 10886399
    Abstract: A semiconductor device, such as a laterally diffused metal-oxide-semiconductor (LDMOS) transistor, includes a semiconductor substrate in which a source region and a drain region are disposed. The drain region has a drain finger terminating at a drain end. A gate structure is supported by the semiconductor substrate between the source region and the drain region, the gate structure extending laterally beyond the drain end. A drift region in the semiconductor substrate extends laterally from the drain region to at least the gate structure. The drift region is characterized by a first distance between a first sidewall of the drain finger and a second sidewall of the gate structure, and the gate structure is laterally tilted away from the drain region at the drain end of the drain finger to a second distance that is greater than the first distance.

  • Patent number: 10816823
    Abstract: The invention relates to a contact lens for use in the treatment of ocular inflammatory pathologies. The contact lens comprises a soft porous material coupled, in certain embodiments, with detoxifying agents. Said material and/or agents contact and neutralize inflammatory mediators present in the tear fluid of ocular pathologies patients. The nature and architecture of the soft porous material allows a greater contact area between the material itself and/or detoxifying agents with inflammatory mediators, in view of the reversible compression of the soft material that allows greater lachrymal fluid turnover and fluid exchange within the contact lens upon e.g. blinking.

  • Publication number: 20200330729
    Abstract: A steerable device for use as e.g. a guidewire for insertion into a subject's body is disclosed. The device features a single side deflection of a bendable portion located at its distal end by application of a longitudinally-directed force either on an inner pull wire or on said bendable portion. The bendable portion is characterized by the presence of a reinforcement structure on one lateral side and a stress relief portion on the opposed lateral side that, upon actuation of the device, allows single side bending thanks to the physical constriction of the reinforcement structure, limiting the compression of one side of the bendable portion. A system further comprising an actuator, as well as methods for using thereof, are also disclosed.

  • Publication number: 20200306523
    Abstract: Described herein are microelectrode array devices, and methods of fabrication, assembly and use of the same, to provide highly localized neural recording and/or neural stimulation to a neurological target. The device includes multiple microelectrode elements arranged protruding shafts. The protruding shafts are enclosed within an elongated probe shaft, and can be expanded from their enclosure. The microelectrode elements, and elongated probe shafts, are dimensioned in order to target small volumes of neurons located within the nervous system, such as in the deep brain region. Beneficially, the probe can be used to quickly identify the location of a neurological target, and remain implanted for long-term monitoring and/or stimulation.
