Abstract:
A collision avoidance method for transmitting data from multiple wireless tire condition sensors on a vehicle is executed by each wireless tire condition sensor having a unique ID and multiple different wake-up times. After the sensor is operated to sense data, the method has steps of reading the ID and computing a determination value with the ID and a variable, selecting one of the wake-up times according to the determination result, and after the selected wake-up time expires, transmitting the sensed data. As the selected wake-up times of the sensors differ from one another, data collision at the receiving end arising from data transmission from the sensors can be avoided. Additionally, besides the wake-up time, a time gap between data transmitted twice consecutively from each sensor can be employed to achieve data collision avoidance.
Abstract:
A device includes a mounting apparatus and a supporting apparatus. The mounting apparatus includes a fixing bracket, an engaging member slidably mounted to the fixing bracket, and an operation member mounted to the engaging member. The fixing bracket defines first and second engaging holes. The supporting apparatus includes a connecting bracket detachably mounted to the fixing bracket. The fixing bracket defines a connecting hole. The connecting bracket comprises a hook. The engaging member comprises a stop piece. The operation member forms a projection. When the engaging member is slid to engage the projection into the first engaging hole, the stop piece moves away from the connecting hole and the first hook extends through the connecting hole. The engaging member is slid to engage the projection in the second engaging hole, the stop piece moves between the connecting hole and the hook to engage with the hook.
Abstract:
A chime bar assembly includes a hollow body with a resonation space defined therein and a top opening is defined in a top of the hollow body. A metal plate is located above the top opening and supported by two rubber plates. A hitting device is connected to the rear end of the hollow body and includes a case which includes lugs to which a pivotal end of a rod is pivotably connected. An operation unit is connected to the case and pushes the pivotal end of the rod so that the sphere is lowered to hit the metal plate.
Abstract:
A time domain symbol timing synchronization circuit is disclosed, which comprises: an autocorrelation function calculator for calculating cyclic prefix autocorrelation functions and an offset time estimator for searching peak positions of cyclic prefix autocorrelation functions to indicate symbol boundary of received communication symbols. The offset time estimator compares a current peak position and a previous peak position. If (a) the difference of the positions is larger than a threshold and (b) the current peak is smaller than a reference average peak, the current peak is determined as false; the offset time estimator weeds out and replaces the current peak position by the previous peak position; and the current peak is not introduced in the reference average peak calculation.
Abstract:
An electrical connector (1) includes a terminal module (32), a metallic shield (31) shielding the terminal module, an outer dielectric cover (10) substantially surrounding the shield and a button (40) attached to the cover. The terminal module includes a mating portion (323) having a number of conductive terminals (322) exposed therein. The shield provides a resilient latching beam (20) at a front portion thereof. The latching beam includes a driving portion (22) and an outwardly extending latching portion (21) adjacent to the mating portion. The cover has an inwardly projecting post (111). The button includes an operating base (43) and an actuator arm (41) being pivotally movable about the post to push the button outwardly.
Abstract:
An electrical connector (100) is provided for mating with a terminal (9) of a mating object and includes an insulative housing (21) and a number of conductive contacts (22) held in the housing. Each conductive contact includes a spring portion (223) and a contacting portion (224) forwardly extending from the spring portion. The contacting portion is supported by the spring portion to be elastically movable in a first direction and a second direction. A contacting point (2240) downwardly bends and extends from a front section of the contacting portion to be brought into mate with a mating object (9).
Abstract:
An electrical connector (1) includes a terminal module (32), a metallic shield (31) surrounding the terminal module, an outer dielectric cover (10) surrounding a major portion of the shield and a pair of a latching mechanism (50) attached to the cover. The terminal module includes a mating portion having a number of conductive terminals exposed therein. The shield includes a resilient latching beam (20) having a driving portion (22) and an outwardly latching portion (21). The latching mechanism includes a button (40) for deflecting the driving portion inwardly to urge the latching portion inwardly toward the mating portion, and a spring (46) and a spring assembled to the button and abutting against the shield for providing enough release strength to push the button to a normal position.
Abstract:
A case (1) is provided for receiving a portable storage peripheral equipment which generally accomplishes signal transmission with a computer. The case includes a case body consisting of a top cover (10) and a bottom cover (20), and a cable assembly (30). Each of the top cover and the bottom cover has a sidewall (14) cooperated with each other. Each sidewall defines a groove (142) therein. The groove of the top cover and the groove of the bottom cover together form a receiving channel (126). The cable assembly has a cable (31) and a cable connector (34) at a free end thereof. The cable can extend out of the case body when the cable connector is in a using state and can be retained in the receiving channel when the cable connector is in an unused state. The case does not occupy external space and is convenient for shipping.

Abstract:
A support for an electronic device includes a mounting apparatus and a supporting apparatus. The mounting apparatus includes a fixing bracket mounted to the main body of an electronic device, an engaging member slidably mounted to the fixing bracket, and a resilient member connected between the fixing bracket and the engaging member. The supporting apparatus includes a connecting bracket detachably mounted to the fixing bracket. When the engaging member is slid relative to the fixing bracket, a stop piece moves away from the connecting hole, and a hook extends through the connecting hole. After the engaging member is released the stop piece moves to the connecting hole to engage with the hook.
