Abstract: A monitoring system and method for early detection of fall risk. A rise-state of a subject occupying a bed is detected. In response to the detection of the rise-state, blood pressure measurement of the subject is triggered. An alarm when the measured blood pressure is not within a selected range of blood pressures.

Abstract: The invention shows a method to control a pointing device with an angular, rate sensor, that comprises generating an ensemble of orthogonal unit vector associated signals by at least one angular rate sensor to represent angular rates in a dimensional space for each mutually orthogonal unit vector direction of said dimensional space, amplifying the at least one of said signal non-linearly for determination of cursor on a screen for (x,y) coordinates of the screen, applying a decision criterion to determine the state of the pointing device as based on said unit vector associated signals. The invention also shows a pointer utilizing the method and a system comprising such a pointer.

Abstract: A device, system and method for monitoring blood pressure information of a user. A device is configured with first and second pressure sensors, a fastening element, and a processing component. In the method the first pressure sensor is detachably attached to a first position and the second pressure sensor to a second position on the outer surface of a skin of the user. The pressure sensor generate signals that vary according to deformations of the skin in response to an arterial pressure wave expanding or contracting a blood vessel underlying the skin. The first signal and the second signal are used to compute at least one output value that represents a detected characteristic of the progressing arterial pressure wave of the user.

Abstract: A device, system and method for monitoring blood pressure information of a user. A device is configured with at least one pressure sensor, a fastening element, and a processing component. In the method the pressure sensor is detachably attached to a position on the outer surface of a tissue of the user. The pressure sensor generates signal that vary according to deformations of the tissue in response to an arterial pressure wave expanding or contracting a blood vessel underlying the tissue. The signal is used to compute pulse wave parameters representing detected characteristics of the progressing arterial pressure wave of the user and blood pressure value of the user.

Abstract: An illuminated decorative cover for a device, and a cellular telephone having such a cover. The illuminated decorative cover includes a cover member having an inner surface and an outer surface, an optical fiber member having an input end and having a side surface adapted to transmit light therethrough, and a light source adjacent the input end of the optical fiber member to emit light from the light source to the optical fiber member for transmission from the side surface of the optical fiber member. The optical fiber member is incorporated with the cover member in a pattern, causing light from the optical fiber member to be visible through the outer surface of the cover member in the pattern when the light source is emitting light.

Abstract: An interchangeable cover piece for a mobile communication device such as a cellular telephone replaces the standard cover piece to enable the mobile communication device to provide a specific functionality such as Global Positioning System (GPS) position location and mapping functionality associated with the interchangeable cover piece.

Abstract: A method and system for transferring data between a phone body and a phone cover having a functionality. The data can be divided into a sequence of bit patterns which can be assigned to different frequency ranges. By arranging the frequencies in a ringing tone according to the sequence of bit patterns, the data is embedded in the ringing tone. The phone cover has a device to receive the ringing tone signal. Based on the sequence of frequencies in the ringing tone signal, the phone cover can retrieve the sequence of bit patterns for effecting the functionality of the phone cover.

Abstract: An IC multiplier circuit has four cells having bipolar transistors to give an exponential input-output function. Each cell has a squaring bipolar transistor and an emitter follower. Differential output signals are taken from the squaring bipolar transistor. The voltage follower is an emitter follower with the bias current through it is substantially larger, e.g. about 10 times larger, than the bias current through the squaring bipolar transistor, which has an emitter resistor.
