Abstract: An optical assembly (100) for use in a wearable device is provided, the assembly (100) comprising: a prism (104), a photonic integrated chip, PIC (108), a substrate layer (106), and a lid (102); wherein the PIC (108) is mounted onto the substrate layer (106); the prism (104) comprising: (i) a first input/output surface (112) optically coupled to the PIC (108), and (ii) a second input/output surface (114) optically coupled to the lid (102), the second input/output surface (114) orientated perpendicularly to the first input/output surface (112), and wherein the prism (104) provides an optical path and reflects a percentage of light from the first input/output surface (112) to the second input/output surface (114). Methods of manufacturing such an optical assembly are also provided.

Abstract: A technique for operating a power subsystem includes determining a respective power status of power devices in the power subsystem. The power devices include a first power device and a second power device that derives power from the first power device. Respective visual indicators of the first and second power devices are controlled to uniquely indicate which of the first and second power devices have an associated fault based on the respective power status of the power devices.

Abstract: A switching regulator sources a power rail and includes a top side or input rail side switch, a bottom side or ground side switch, and an inductor. When the switching regulator is disabled or generally turned off, a bottom side transistor in the bottom side switch is pulsed on and off, or held on, to drain or bleed the power rail to ground. When the bottom side transistor is off and if there is a voltage across the inductor from the power rail at a switching node, current flows through a body diode of the top side switch to the input rail of the switching regulator.

Abstract: Embodiments of the present invention disclose an apparatus including a power source and a plurality of electronic subsystems connected in parallel to the power source. Each of the plurality of electronic sub systems includes a circuit breaker, a transient-voltage-suppression (TVS) diode, and a load. The TVS diode is located downstream of the circuit breaker in each of the plurality of electronic systems.

Abstract: A window frame profile for forming into a window frame with a number of other similar profiles includes a separate nailing strip extruded from aluminum and attached to the outer surface of the frame profile. The nailing strip includes a planar strip member and a cylindrical bead portion along one side edge of the strip member. The bead is snap fastened into a cylindrical recess in the outer surface of the frame allowing rotation of the strip about the axis of the bead from a retracted position for transport in which the strip is received in a flat recess on the outer surface. The strip can be rotated from the retracted storage position to an erect position at right angles to the outer surface by rotation about the axis of the bead and snap fastened in the erect position.

Abstract: A window frame system includes four basic profiles for new building construction and for various other projects including renovation, bow and bay constructions. One profile includes an outer profile for engagement with the wall of a new building in which the distance between the inside wall of the profile and a nailing fin is at least 6.5 inches. The height of the profile is then reduced to accomodate this larger width. A cross mullion is provided and a sash frame profile is also provided. The inner wall of the outer frame and the side walls of the mullion are arranged for cooperation either with a picture window unit or with the sash frame. The fourth profile comprises a renovation/bow profile which can be inserted into an existing window frame or can be snapped together alongside similar profiles to form a bow or bay construction.
