摘要:
An apparatus for distance computation includes a location determining device for determining a current location based on signals received from a positioning broadcast system; a memory for storing a coordinate of at least one reference location and at least one program for the distance computation; an input device for entering the coordinate of the at least one reference location; a microprocessor for calculating a distance between the current location and the at least one reference location, the microprocessor operatively coupled to the location determining device and the memory; and an output device operatively coupled to the microprocessor for outputting the calculated distance. The apparatus may further include an alarm setting device operatively coupled to the microprocessor for determining an alarm condition from the calculated distance; and an alarm triggerable by the alarm setting device.

An interface and a system for interconnecting a car alarm and a wireless telephone include an alarm connector for connecting to an alarm and a mobile station connector for connecting to and sending signals to a wireless telephone connector. The wireless telephone has a memory storing a telephone number of a recipient to be notified when signaled through the connector of the wireless telephone. A processor (CPU) interconnects the alarm connector and the mobile station connector. The processor (CPU) signals the wireless telephone to dial the telephone number when the alarm is tripped and sends signals through the alarm connector to the processor (CPU).
摘要:
A person-individual emergency recognition system, having at least one sensor for detecting at least one mechanical or other physical event having an effect on the person and for triggering a safety function, in which the at least one sensor is connected to a transmitter with which the safety function may be triggered at a predefinable or arbitrarily selectable distance with respect to the event location. The transmitter is preferably a component of a conventional mobile radio-communication system, and a device is provided for determining and transmitting the event location, for example, using a conventional global positioning system.

A local wireless device serves as a unique identifier for students and teachers in a school system. The school is equipped with multiple stationary hubs for tracking the location of students and teachers. The school may also be equipped with multiple mobile hubs, such as hand-held hubs and hubs on school buses, which allow easily and quickly determining if a student or teacher is where he or she should be. The local wireless device may be used in conjunction with a pager, mobile phone, a voicemail device, and devices for storing, reviewing and sending audio and video files. The preferred embodiments also includes a single device that provides all of the above-mentioned functions. In addition, a wireless display may be coupled to the local wireless device as needed. The function of these devices may be controlled according to the needs of the system. For example, some of the functions may be disabled during class periods, but enabled between classes. The preferred embodiments thus disclose many different wireless devices that are all integrated into the school's computer system to customize their function according to the needs of the school.
摘要:
A control and detection system for control of an object connected to the system, and for detection of object location in case of disappearance, theft or shifting of object, whereby the system has communication from each object at least to one data receiving device (3), (6) and from there data transmission (7) to the control unit. The system comprises an active short range transmitter that can be activated for function, furnished with a code of its own and placed in an object in the control area, a safety module monitoring the presence of the transmitter placed in an object in the area and/or detects a sender arriving to the area, base station of communication with connection to the control centre and the safety module.

An apparatus is provided for warning when a child has been left in a baby car seat and when one or both of: (i) a vehicle door has been opened, and (ii) a key ring remote unit is not within a predetermined zone about the vehicle. The apparatus includes a child detection mechanism for detecting the presence of a child within a baby car seat located within the vehicle; a door position detection mechanism for detecting the state of the driver side door of the vehicle; a range detection mechanism for detecting the range of a key ring remote from the vehicle; a control unit for generating an alarm signal when the child detection mechanism detects the presence of a child within the infant seat and either or both: (i) the door position detection mechanism detects that the state of the driver vehicle door position has been modified from a nullclosednull position to some other position, and (ii) the range detection mechanism detects that the key ring remote is no longer within the predetermined range from the vehicle; and alarm units for generating an alarm or alarms in response to the alarm signal.

A system and methodology for a programmable and reprogrammable locating system comprising of at least one central control unit and at least one response unit. The central control unit, for activating the response unit and for programming/reprogramming the response unit, utilizes a serial bits stream signal to communicate the programming data and activation data to the response unit. Both the central control unit and the response unit utilize the generation of a square wave for discriminating between a signal as coming from a central control unit from those signals emanating from non-central control unit sources. This signal discrimination capability and signal data carrying capability allow multiple response units to be programmed/reprogrammed to one or more central control units. This programmable/reprogrammable capability gives universal adaptability in that the response unit circuitry/central control circuitry can be incorporated directly into or associated with other goods that previously lacked locating abilities. The invention's ability to be incorporated into a multitude of different goods would allow the wide spread dissemination and application of locating technology.
摘要:
A system and method of identifying and removing artifact from radio frequency noise from biopotentials identifies epochs contaminated with radio frequency noise. Contaminated epochs are then replaced with recent uncontaminated epochs stored in a buffer, depending on the current level of artifact and the availability of suitable data. Discontinuities arising at the beginning of the replaced epochs are smoothed by means of a windowing function.
