The method and device help avoid traffic accidents and violations through significant enhancing safety and convenience of driving by providing a far better rear and side observation including in darkness, and reliably prevent, if an accident/violation occurs, from misjudging, owing to an unbeatable legal evidence through recording the objective pattern of the accident/violation . It is accomplished by positioning into a vehicle an onboard digital camera having at least one lens with a photo-receiver, shooting permanently the surroundings at an predetermined frequency, showing images captured on at least one onboard screen, and making the running sequence of images through digital memory so that a latest image captured is recorded and stored in digital memory expelling an oldest one and the overall amount of the images and, hence, duration of time recorded does not change. When responding to an accident/violation, at the instant of occurrence plus a predetermined delay, shooting stops (either automatically by an impact of a collision, or manually), and digital memory retains the congealed sequence of images just before, during, and shortly after the event.

The present invention provides a memory chip for use in an oximeter sensor, or an associated adapter or connector circuit. The memory chip allows the storing of different data to provide enhanced capabilities for the oximeter sensor. In addition to providing unique data to store in such a memory, the invention describes unique uses of data stored in such a memory. The data stored in the memory chip may include information relating to use of the oximeter sensor. For example, the memory chip may encode a sensor model identification that can be displayed on a display screen when the sensor is connected to an oximeter monitor. The memory may also encode a range of operating parameters such as light levels over which the sensor can function or a maximum drive current. The operating parameters are read and interpreted by a controller circuit to control the pulse oximetry system.

Converter circuitry converts data stored in digital memory to an analog signal which is magnetically coupled to the read head of the equipment. Numerous sensors detect changes in at least one of the tape equipment mechanisms in the audio cassette emulator.

A system is described for automatically adjusting various adjustable devices in an automotive vehicle such as the seats, mirrors, pedal positions and the like. The system includes a physiological characteristic scanner which generates an output signal representative of that physiological characteristic of the person seated in the driver seat and, optionally, in the passenger's seat. Such physiological characteristics includes, for example, retinal scanners, fingerprint readers, thermal scanners and the like. The output signal from the physiological characteristic determining device is coupled as an input signal to a processor which also has access to digital memory containing data representing the physiological characteristics of authorized drivers of the automotive vehicle. This memory further includes data representative of the various position(s) of the adjustable device(s) for each authorized driver and optionally passenger of the automotive vehicle. Thus, upon identification of the authorized driver/passenger from his or her physiological data, the processor automatically generates position signals to the various adjustable devices in order to move the adjustable devices to preselected positions suitable for that particular authorized driver or passenger. In one embodiment of the invention, the system also monitors and stores the amount of time spent by the driver or passenger of the vehicle in the vehicle.
