摘要:
Disclosed are a method, device, and system for a microelectromechanical (MEM) device control system that can control the operation of a MEM device. The system can include a microelectromechanical device and a control circuit. The micromechanical device can include a moveable member coupled to an electrical terminal, a sensor, responsive to a movement of the moveable member, can output a sensor signal based on the movement of the moveable member, and an actuating electrode for receiving a control signal. The control circuit can be responsive to the signals output by the sensor and outputs the control signal to the actuating electrode.

A garment hanger (10) has at least one arm (12) connected to a suspension portion (11). The garment hanger has a first moulded portion (20), forming a first proportion of the at least one arm and suspension portion, mated and joined to at least a second moulded portion (40), forming a remaining second proportion of the at least one arm and suspension portion, to form a hollow, enclosed monocoque structure. The garment hanger may be provided with fingers (830) to which loops or straps of a garment may be attached to suspend the garment from the garment hanger thereby. Alternatively, or in addition, the monocoque garment hanger may include engagement means (730) for engaging a suspension hook of a further garment hanger such that the further garment hanger may be suspended from the monocoque garment hanger.

A system for golf data collection comprises an apparatus arranged to be worn about the body of a golfer during a game of golf. The apparatus includes a positioning system for determining various locations of a golfer during the game, a tag reader for reading a club held in close proximity to the apparatus around the time of striking a golf ball, and a processor for correlating the location of the golfer with the time at which a tag is read to enable the path of a golf ball throughout the game of golf to be determined.
摘要:
A sealed capacitive sensor includes a substrate having a diaphragm forming a first plate of a capacitor; a second fixed plate of the capacitor spaced from the diaphragm and defining a predetermined dielectric gap and a sealing medium connecting together the substrate and fixed plate in an integrated structure and hermetically sealing the gap.

An injection molding apparatus 80 has a cavity 64 and core 65 co-operatively defining a void of inverted J-shape transverse cross-section for molding a garment hanger 10. A first leg 115, 127 of the J-shape cross-section forms a front of the garment hanger, a base 111 of the J-shape cross-section forms a transversely arcuate upper face of the garment hanger for receiving shoulders of a garment to be suspended from the garment hanger and a second leg 116, 126, opposed to the first leg, and substantially shorter than the first leg, forms a return rear portion of the garment hanger. A garment hanger molded in the injection molding apparatus is also disclosed.
摘要:
Protocols and architecture for secure virtual private networks. Intraenterprise data communications are supported in a secure manner over the Internet or other public network space with the implementation of secure virtual private networks. Members of a virtual private network group exchange data that may be compressed, encrypted and authenticated, if the exchange is between members of the group.
摘要:
A capacitive sensor including a housing having a hermetically sealed cavity, a plate in the cavity, a diaphragm forming a part of the cavity and spaced from the plate, a conductive layer on the first diaphragm, and a second conductive layer on the plate, the first and second conductive layers being the electrodes of a capacitor whose capacitance varies with the position of the diaphragm relative to the plate.
摘要:
A garment hanger has a body (1) with a longitudinal axis. A movable first arm (2) is slidably mounted on the body for free movement with respect to the body substantially along the longitudinal axis. A constant or decreasing force spring (4) applies a resilient force to the first arm to urge the first arm outwards of the body so that the first arm is able to move between a retracted position and an extended position relative to the body. The resilient force exerted by the garment hanger remains substantially constant or increases between a fully retracted position and a fully extended position.
摘要:
A chopped charge pump with matching up and down pulses including a first pair of current sources, a second pair of current sources, and a switching circuit for switching on in a first phase one of each pair to provide up current pulses and the other of each pair to provide down current pulses and switching on in a second phase the other of each pair to provide up current pulses and the one of each pair to provide down current pulses to offset error in the current response of the pairs of current sources.
摘要:
A thin-film bulk acoustic wave delay line device providing true-time delays and a method of fabricating same. An exemplary device can comprise several thin-film layers including thin-film transducer layers, thin-film delay layers, and stacks of additional thin-film materials providing acoustic reflectors and matching networks. The layer material selection and layer thicknesses can be controlled to improve impedance matching between transducers and the various delay line materials. For example, the transducer layers and delay layers can comprise piezoelectric and amorphous forms of the same material. The layers can be deposited on a carrier substrate using standard techniques. The device can be configured so that mechanical waves propagate solely within the thin films, providing a substrate-independent device. The device, so constructed, can be of a small size, e.g. 40 μm per side, and capable of handling high power levels, potentially up to 20 dBm, with low insertion loss of approximately 3 dB.
