Abstract:
An automobile steering lock includes a steering wheel lock (2), provided with a base (20), a locking portion (21) and a stationary rod (22). The base (20) has a through groove (23) bored with a dead bolt hole (232) on its inner sidewall. A pressing lock core (24) located outside the base (20) has a dead bolt (240) to be inserted into the dead bolt hole (232). A restricting plate (25) fixed on a bottom of the through groove (23) has a sliding rail (251) and plural through holes (250). A locking member (26) has a sliding rod (260) formed at its top for being fitted in the through groove (23), a through hole (261) bored through the sliding rod (260) for being inserted by the dead bolt (240), and at least one sliding groove (262) cut near a bottom of the sliding rod (260). The locking member (26) also has a blocking plate (263) at a bottom. The steering wheel lock (2) is easy to use but uneasy to be broken, achieving anti-theft purpose. The sliding groove (262) cooperates with the sliding rail (251).
Abstract:
A calling-help warning device of a third brake light of an automobile includes a remote controller (1) and a calling-help warning device (2). The remote controller (1) has at least one battery (10), a switch (11), a plurality of control buttons (12) and a wireless signal emitter (13) that are sequentially linked up. The calling-help warning device (2) is provided with a wireless signal receiver (20), a control unit (21), at least one inductor (22), a third brake light (23), a setting switch (24), a plurality of brake lights (25), and a power supply (26). If a car is parked, a driver can utilize the remote controller (1) to activate the calling-help warning device (2). If the car is intruded by a thief, the at least one inductor (22) can activate the third brake light (23) to keep on flashing to warn people thereabout for help.
Abstract:
A vehicle anti-theft SOS-calling device includes at least one SOS-calling device (1) having a control unit (10), anti-theft detecting unit (11), a rescue signal lamp board (12) and a remote controller (2) having a main controller (20), at least one switch (21), and an alarming unit (22). The control unit (10) has a wireless receiver (13) and a wireless transmitter (14); the main controller (20) has a wireless transmitter (23) and a wireless receiver (24). The rescue signal lamp board (12) has light emitters (120) in a shape of a word meaning rescue and fixed clearly visible on a vehicle body. The SOS-calling device (1) is turned on and off by the remote controller (2) to send signals to the control unit (10) to light up the rescue signal lamp board (12) and simultaneously the wireless transmitter (14) of the SOS-calling device (1) transmits signals to the wireless receiver (24) of the remote controller (2), so that the data of the signals is shown on the alarming unit (22), indicating the vehicle being stolen.

Abstract:
One embodiment provides an offset calibration circuitry configured to compensate an offset voltage of a resistive bridge sensor. The offset calibration circuitry includes a first current digital to analog converter (IDAC) coupled to a first successive approximation register (SAR), a second IDAC coupled to a second SAR and an SAR controller circuitry. The first IDAC is configured to couple to a negative voltage port of a resistive bridge sensor. The first SAR is configured to store a first digital value. The second IDAC is configured to couple to a positive voltage port of the resistive bridge sensor. The second SAR is configured to store a second digital value. The SAR controller circuitry is configured to adjust each bit of the first SAR and each bit of the second SAR based, at least in part, on an output of a comparator. The comparator is configured to compare a voltage on the negative voltage port or a voltage on the positive voltage port to a common mode voltage.
Abstract:
An improved drain board for use on a gutter particularly has a cover board Pivotally secured to a mounting bracket. The cover board has an outwardly extended pivot pole at one corner thereof and an inwardly extended receiving tube at the opposite corner for accommodation of a bias spring and a movable pivot rod. At the corresponding corners of the mounting bracket is disposed an outwardly extended engaging tube respectively so as to permit the fixed pivot pole and the movable pivot rod of the cover-borad to be pivotally mounted onto the mounting bracket and the cover board is well protected from being stolen with ease by burglars.
Abstract:
A phase frequency detector includes a phase error detector outputting a phase error signal according to a first input signal and a second input signal; a phase error judgment unit outputting a phase error judgment signal according to the first input signal and the second input signal; and a reset unit outputting a first reset signal to reset the phase error detector, and outputting a second reset signal to reset the phase error judgment unit, according to the phase error judgment signal.
Abstract:
A method of adjusting a sampling condition to generate a sampling clock in an analog to digital converter includes performing an analog to digital conversion on an analog input signal to thereby produce a digital sampled signal having a plurality of samples; calculating a difference value between two adjacent samples in the digital sampled signal; comparing the difference value with a threshold; adding the difference value into a sum of differences value if the difference value is greater than the threshold; and generating the sampling clock for the analog to digital converter according to the sum of differences value.
