Abstract: Aspects of the disclosure are directed to a digital design with bundled data asynchronous logic and body-biasing tuning. In one aspect, implementation includes establishing a control path between a first controller and a second controller using a handshaking protocol; establishing a data path between a first latch and a second latch using a bundled data technique; executing a first dynamic body biasing tuning by applying a first body bias signal to the control path; executing a second dynamic body biasing tuning by applying a second body bias signal to the data path. The digital design includes a first controller with a control path to connect to a second controller, wherein a first body bias tuning signal tunes body bias in the control path, a first latch with a data path to connect to a second latch, wherein a second body bias tuning signal tunes body bias in the data path.

Abstract: The invention provides a valve having an elongated main body and a substantially flat area defined within the valve between its first and second ends; wherein a stopping screw is received in said flat area so as to prevent extraction of the valve from a casing by applying a force against a portion of the valve once the valve is moved a predetermined number of turns. The invention also provides a method for inhibiting the turning of a valve having the steps of installing a threaded portion of a valve in a first threaded aperture through a casing, where the first threaded aperture receives the threads of the threaded portion of the valve; and threading a screw through a second threaded aperture in an exterior of the casing, where the screw, is disposed in a position to come into direct contact with the valve after a predetermined number of turns.

Abstract: A carpet air kicker comprises a body, a rod, a spring and a controlling switch. The body defines an interior chamber including a front chamber and a rear chamber. A front end and a rear end of the rod have a gripping head and a piston respectively. The piston is located in the interior chamber such that the front chamber is not communicated with the rear chamber. A piston assembly of the body is connected to the rod and located between a front end of the body and the front chamber. The spring is installed in the rear chamber. A communicating hole is communicated with the front chamber. The controlling switch controls the front chamber communicated with external air such that the spring pushes the rod moving forward or communicated with an air compressor such that an air pressure pushes the rod moving backward.

Abstract: Embodiments of the invention described herein include low cost infusion devices having basal and/or bolus fluid delivery options. Embodiments of the device include a housing, a reservoir to contain the fluid, a source of pressure to exert a force to expel the fluid contained in the reservoir, a bolus port adapted to receive an optional extra dose of fluid, and a cannula in fluid communication with the reservoir and the bolus port. The cannula is adapted for insertion into the user's skin for delivery of the fluid to the user's body. The device can provide a continuous delivery of the fluid along a first fluid flow path from the reservoir to the cannula and the optional extra dose of fluid along a second fluid flow path from the bolus port to the cannula.

Abstract: The present invention relates to a bicycle parking lock apparatus adapted for locking a crank of the bicycle. The apparatus includes a primary lock part and a secondary lock part movable reciprocatingly relative to the primary lock part. The primary lock part defines a recess adapted to receive the crank. The recess is provided with a sidewall such that when the crank is received in the recess, an outboard side of the crank at a first end thereof is shielded by the sidewall. The secondary lock part is adapted to hold the crank in position in cooperation with the primary lock part.

Abstract: A face insert for golf club head in one embodiment can comprise a substrate comprising a score line groove-free front surface. A cover layer is provided at least on the front surface of the substrate. The cover layer can alternatively overlay at least a portion of the peripheral edge of the substrate. The cover layer comprises a ball-striking surface spaced by the cover layer from the substrate. Plural elongated score line grooves can extend into the polymer layer from the ball-striking surface. In addition, visible markings are interposed between the cover layer and the front surface of the substrate, the visible markings being visible through the cover layer. In one form the visible markings comprise elongated score line markings and target markings in a central portion of the substrate. The visible markings can be screen-printed markings, which are then protected by the cover layer from wear. The cover layer can be molded and can be a polymer layer.

Abstract: Various embodiments of the disclosure relate to an optical system that includes a base unit and one or more cartridges that are removably attachable to the base unit. The one or more cartridges can include optical components configured to output a beam of light (e.g., a laser). The base unit can be configured to combine multiple beams of light (e.g., emitted by multiple cartridges) and output a combined beam of light. The cartridges can be interchanged to modify the light output by the optical system. The optical system can include thermally one or more stable enclosures and/or a temperature controller. The optical system can include one or more alignment adjustment optical components configured to adjust the alignment of one or more light beams.
