Abstract: A blood pressure sensor includes a source of photo-radiation, such as an array of laser diodes. The sensor also includes a two-dimensional, flexible reflective surface. The reflective surface is nominally positioned relative to the radiation source such that the radiation travels in a direction normal to the reflective surface. The reflective surface is placed adjacent to the location on the patient where the blood pressure data is to be acquired. Radiation from the source is reflected off of the reflective surface onto a two-dimensional array of photo-detectors. Systolic and diastolic blood pressure fluctuations in the patient are translated into deflections of the patient's skin. These deflections cause corresponding deflections in the two dimensional reflective surface. The associated movement of said flexible reflective surface due to blood pulsation causes scattering patterns from said reflective surface to be detected by the two dimensional array of photo-detectors. The output from the array of photo-detectors is calibrated to blood pressure in mmHg during a calibration procedure to obtain a set of calibration relationships for one or more of the individual detectors. The calibration relationship are then used during acquisition of blood pressure data to arrive at blood pressure data.

Abstract: A device (100) includes detachable main and auxiliary batteries (101, 102) and a circuit (310) for discharging and charging the batteries (101, 102). Discharging is accomplished by an auxiliary switch (420) that connects the auxiliary battery (102) to power the device (100), a detector (422), and a main switch (424) that connects the main battery (101) to power the device (100), without interruption, when the auxiliary battery (102) drops below a predetermined voltage (508) as determined by a detector (422). Charging is performed by switches (440, 442, 446), an internal charger (444), and a controller (306). When both batteries (101, 102) are attached, the controller (306) uses the switches (440, 442, 446) to select and couple charging current generated by the internal charger (444) to the main battery (101). Once charged, the controller (306) switches to charge the auxiliary battery (102).

Abstract: A bidirectional voltage translator (102) includes a first port (200/400), a second port (202/402) and a bidirectional translator circuit (208-215/404-408, 410, 412-415) coupled between the first and second ports (200/ 400, 202/402). The first and second ports (200/400, 202/402) communicate signals at a first voltage level and a second voltage level, respectively. The second voltage level is different from the first voltage level. When a first port signal input at the first voltage level at the first port (200/400) is detected, the bidirectional translator circuit (208-215/404-408, 410, 412-415) translates the first port signal into the second voltage level at the second port (202/402) and disables translation of a signal at the second port (202/402) to the first port (200/400). When a second port signal input at the second voltage level at the second port (202/402) is detected, the bidirectional translator circuit (208-215/404-408, 410, 412-415) translates the second port signal into the first voltage level at the first port (200/400) and disables translation of a signal at the first port (200/400) to the second port (202/402).

The switch circuit (310) is coupled to the first port (300/302) and the second port (302/300). The switch circuit (310), responsive to the first signal at the first voltage and the second signal at the third voltage (V2/V1), communicates to the second port (302/300) the second signal at the first voltage. The switch circuit (310), responsive to the second signal at the first voltage and the first signal at the second voltage (V1/V2), communicates to the first port (300/302) the first signal at the first voltage.

Abstract: A portable cellular radiotelephone (100), which is powered by main and auxiliary batteries (101, 102) in an operating state. The main and auxiliary batteries (101, 102) include respective memories (402, 410) for storing a 64- bit registration number and 1024 bits of data for identifying the type and brand of such batteries. Memories (402, 410) store a laser-engraved 64-bit registration number and 1024 bits of data. In order to uniquely identify the batteries (101, 102), the 64-bit registration number includes a twelve-bit brand code having a predetermined brand code value and an eight-bit type code having a predetermined type code value, and the 1024 bits of data include a unique multi-character message. By identifying the unique brand code, type code and multi-character message when a battery is inserted into portable device (100), it can be insured that the portable device (100) will be operated with a reliable and safe battery. Otherwise, the portable device is turned off and the battery is not charged.
