Intelligent electrical devices

An electronic circuit for use with an exhaustible power source and at least one load such as a light bulb, a radio or motor, includes a microchip with an input that transmits a signal to the microchip when the load is activated or deactivated. The input does not form a serial link between the power source and the load. The power switch, by on / off switching, controls energy flow from the power source to the load. The input to the microchip acts as an activation / deactivation user interface. The microchip allows the user to select a specific load, specific functions for the selected load based on the time duration of activation signals, the time duration between activation signals and the number of activation signals at the input.

The input does not form a serial link between the power source and the load. The power switch, by on / off switching, controls energy flow from the power source to the load. The electronic circuit has an automatic delayed shut-off function for the load and, a find-in-the-dark indicator and a power source level indicator which are active when the load is not energized and the power source is not being charged. The input to the microchip acts as an activation / deactivation user interface. The microchip allows the user to select specific functions based on the time duration of activation signals, the time duration between activation signals and the number of activation signals at the input.

Vehicle brake efficacy monitoring and alarm system

A vehicle brake effect motoring and alarm system belongs to the technical field of vehicle electron and safety. The outputs of a vehicle brake pedal displacement sensor and a vehicle brake pressure sensor are respectively connected with the input of an information collection and control unit; the output of the information collection and control unit is connected with the signal input of an alarm device. Due to being corresponding to the stroke of a brake pedal, the information collection and control unit carries out evaluation on the brake effect risk degree R of the vehicle according to a vehicle brake pressure signal BPact that is actually collected by the information collection and control unit as well as a benchmark brake pressure signal BPline2, and gives an alarm to a driver by transmitting a signal to an alarm device according to the evaluated risk degree R. The information collection and control unit is Motorola MC9S08DZ60. The vehicle brake effect motoring and alarm system improves the reliability of the system, has great help on preventing the traffic accidents caused by the losing and reducing of the brake effect, can adopt grading alarm according to the damaged degree of the brake performance, is simple in system structure, is easy to be achieved and has low cost.

Flesh conducted sound microphone, signal processing device, communication interface system and sound sampling method

When non-audible murmurs are to be obtained with maximum possible fidelity, the attenuation of the high frequency region attributable to mismatching of acoustic impedance on the interface between the skin surface over soft tissues in the body, which are mainly liquid, and the air space, which is gaseous, is restrained. The attenuation of the high frequency region attributable to mismatching of acoustic impedance can be restrained by installing a microphone on a surface of the skin immediately below the mastoid of a human, and sampling with condenser microphone portion via hardened silicone rubber or the like muscle-conduced vibrations of non-audible respiratory sounds articulated along with motions (motions of the mouth) not involving regular vibrations of the vocal cords.
