Abstract: A voice recorder with sound reminder, the voice recorder comprises a central processing unit, a switch module, a memory module, a voice recording module, a speaker module and a display module; the user presses the setting button for setting the switch module, and the outer data of acoustic wave is transmitted to the central processing unit by the voice recording module, and the user programs time of the timer through the number that the user presses the setting button to record the voice in certain sections. The central processing unit saves a plurality of voice data and writes the data into the memory module; the signal is transmitted to the central processing unit while the time is on the predetermined schedule. The central processing unit reads the voice recorded data in the memory module according to the received signal, and plays the voice that was preliminarily recorded.

Abstract: An intelligent microwave detecting system comprises: a power supply source for supplying the electric power to a passive electric equipment which is connected to the power supply source, an output controller connected to the circuit including the power supply source and the passive electric installation so as to control operation of the passive electric installation, a microwave detector connected with the output controller to transmit all-directional microwave to a defined three dimensional space so as to detect the state of moving objects therein and send a detection signal to the output controller for judging should the passive electric installation be actuated. The microwave radiated from the microwave detector is all-directional and capable of piercing through the building structure and is resistant to the environmental interference therefore a wide range and precise detection can be expected, besides, the detector of this type can detect non-heat generating intrusion objects.

Abstract: A method and devices that apply radio frequency remote control device to find objects, the major part of the present invention is a radio frequency remote control device which is mounted at a fixed position. The radio frequency remote control device has an internal timing device, for special purpose users such that the device can make audible and/or visible warning signals to remind the user of the time of medication. By applying the working principle of radio frequency transmitting and receiving function, when the setting time has arrived or the user presses a button, the radio frequency remote control will emit a coded signal according to the receiving instruction. This signal is the received by a receiver. After decoding, if the signal is correct, the warning device in the receiver will emit audible and/or visible signals to allow for the user to locate the object. Thus achieve the convenience of modern life.

Abstract: An automatic door lock for a vehicle is arranged to lock the door of the vehicle following starting of the vehicle and performance by the driver of another action, such as stepping on the brake pedal of the vehicle in preparation for placement of the vehicle in gear, thereby ensuring that automatic door locking will occur even after the driver exits and re-enters the vehicle after starting it to permit the vehicle to warm up before driving away. The controller may also be programmed to lock the vehicle doors immediately following turning of the ignition, in situations where the brake pedal would not necessarily be pressed prior to placing the vehicle in gear, such as in the case of a manual transmission.

Abstract: The casing of a passive proximity transceiver includes a protrusion which extends from the main body of the casing to prevent metal objects from touching the main body, where they would otherwise be close enough to interfere with reception of signals transmitted between the passive proximity transceiver and another electronic device. The casing may be arranged to be mounted on a key ring, with the protrusion being in the form of a collar extending around the main body.

Abstract: A low frequency vibration sensor includes a permanent magnet, a sensor body, a steel spheroid, and a piezoelectric element. The sensor body has a pillar shape and is made of plastic material having a transverse separator section in a middle portion to divide the sensor body in an upper and a lower spaces. A depressed slot is formed around the upper space for disposing the magnet, while the lower space is made larger than the steel spheroid so as to accommodate it therein movably and also put under the influence of an attractive force of the magnet above. A piezoelectric element is set in along a grooved rail provided around the bottom edge of the sensor body to thereby form a closed space. The steel spheroid is movable to swing in the space such that its motion is conducted to the piezoelectric element to induce a corresponding low frequency electric signal between two electrodes of the piezoelectric element to thereby detect the vibration caused by an external force.

Abstract: A vehicle security device of the present invention comprising of a remote control, a receiver/decoder section, a CPU, and an amplifying section. It has been designed to arm in two ways--by remote control, and by timer. By pressing the button #1 of the remote control, the vehicle security device will be armed. The vehicle security device has two separate counters--the 10 minute counter, and the 30 second counter. No matter doors are close or open, the 10 minute counter will start counting after turning off ignition and will continue counting even if a door is opened while the 30 second counter will only start counting if any door of the car is opened and closed (provided all the remaining doors are close) but will stop counting if any door of the car is opened. The vehicle security device will arm itself if any of the two counters finished counting (whichever finished first). However, if the ignition is turned on during countdown, the car can be started and both counters will stop counting.

Abstract: A security system uses an ordinary switch, which may be an existing switch such as a parking light switch, to enter digits of a security code, with the beginning of a digit being indicated by turning on the ignition switch and the end of a digit being signified by turning off the ignition switch. Entry of the security code can be used to perform an emergency system disarm when the remote control transmitter is lost, to change the security code when the transmitter is in the possession of the owner, and to teach a new transmitter.

Abstract: An anti-hijack security system which automatically protects the vehicle with anti-hijack after the ignition has been turned off for a predetermined long period of time or after the ignition has been turned off and a door has been opened and closed for a predetermined short period of time. Thus, ensuring the owner to have anti-hijack protection when he returns to his vehicle. The anti-hijack protection system also makes sure that, once triggered, it will perform the anti-hijack trigger sequence even if a door sensing device is damaged or if a door is not closed properly. The system also makes sure that once anti-hijack trigger sequence is in it's last few stages, it cannot be disarmed by simply pressing the arm/disarm switch but can only be disarmed by entering a security code.

Abstract: A car security system capable of sending out an alarm when a car door is opened by an unauthorized person comprises a power stabilizing circuit for providing working DC power for the security system, a signal amplifying circuit for detecting small voltage change signals in the car battery and for generating therefrom an amplified signal, an alarm circuit including a buzzer and a controlling transistor, a microprocessor for receiving and then evaluating the amplified signal. In operation, when a car door is opened, a voltage change signal is produced, which is then detected for evaluating whether the opening of car door is authorized. If a voltage change signal is detected during conditions other than the car door opening, it is identified as a false alarm.

Abstract: A shock sensor includes an inductance coil, a magnet, a magnetically soft material, and a support bracket for the magnetically soft material. The inductance coil and the magnet are fixed relative to each other. The magnetically soft material has one side thereof fixed on the support bracket and lies relative to the coil and the magnet so that the magnetically soft material can move up and down as well as leftwardly and rightwardly and inwardly and outwardly when the shock device vibrates and thereby alter a magnetic flux from the magnet to the inductance coil so as to generate signals responsive to the fluctuations of a magnetic flux.
