Abstract: A method for enhancing downhole telemetry performance comprising enhancing a signal in order to offset signal-to-noise ratio reduction with increasing measured depth, wherein the signal is modified at specified measured depths which are inferred from acoustic wave velocity determination.

Abstract: Registering energy consumption in part of a building, an item of state information of at least one energy load being acquired, the state information being transmitted to a control center, and the state information, a state duration and a specific statement of the consumption of the energy load being used to determine and evaluate the energy consumption in the control center. It is possible to dispense with separate energy consumption measuring units as a result of the energy consumption being registered by multiplying the switched-on duration by a specific statement of the energy consumption (that is to say power) of the energy load.

Abstract: A programmable telemetry circuit that may be programmed for high bandwidth, low Q; low bandwidth, high Q; or for other parameters. The programmable telemetry circuit may include a first coil; a high impedance path having a first node connected to a first node of the first coil; a low impedance path having a first node connected to the first node of the first coil; a capacitive path having a first node connected to a second node of the first coil; and an input path for coupling signals into the high impedance path, the low impedance path, and the capacitive path. The low impedance path may be connected in parallel with the high impedance path. The capacitive path may form a circuitous path with the high impedance path and the low impedance path. The programmable circuit may be programmed to select the high impedance path or the low impedance path.

Abstract: A radio control transmitter for a model is disclosed wherein a control range is limited to not to exceed a maximum control range without using a mechanical means. In accordance with the transmitter, an added control range being a sum of two or more of the control ranges is calculated, whether the added control range exceeds a maximum control range set to correspond to the operating section of the object to be controlled is determined, and the control range is corrected when the added control range exceeds the maximum control range.

Abstract: A drill pipe having a box end having a tapered thread, and an internal shoulder and an external face for engagement with a drill pipe pin end having a tapered mating thread, and an external shoulder and an external face adapted for data acquisition or transmission. The relative dimensions of the box and pin ends are precisely controlled so that when the tool joint is made up, a repeatable reference plane is established for transmitting power and tuning downhole sensors, transducers, and means for sending and receiving data along the drill string. When the power or data acquisition and transmission means are located in the tool joint, the dimensions of the tool joint are further proportioned to compensate for the loss of cross-sectional area in order maintain the joints ability to sustain nominal makeup torque.

Abstract: The invention is a computer system with a button array on the computer chassis for simulating the operation of common consumer electronic devices. Each button of the array of buttons is hardwired to the system processor. Upon activation of one of these buttons, an interrupt signal is sent to the system processor. The system processor halts whatever it is doing, and subsequently identifies the activated button. A signal generator attached to the buttons then sends the system processor a second interrupt signal, such that upon exiting the handling of the first interrupt, the system processor is presented with a second interrupt. The system processor then handles the second interrupt. While handling this second interrupt, the system processor executes whatever function corresponds to the activated button. The system processor then exits the handling of the second interrupt and resumes whatever activity it was engaged in before the activation of the button.

Abstract: A device for prevention of ulcers in the feet of diabetes patients is embodied in a footwear article such as in a shoe. The device includes a sensor disposed in a contained liquid mass of a hydrocell carried in the shoe inner sole, the sensor being one that detects both pressure and temperature values to which the patient's feet are exposed. The sensor includes a bridge circuit comprised of four piezoresistors arranged in two diagonally arrayed pairs, the resistance of one pair of resistors increasing and the resistance of the second pair decreasing in the presence of an increase in the pressure condition in the hydrocell, the resistance of all the resistors increasing or decreasing responsive to respective increases and decreases of temperature in the hydrocell.

Abstract: An infrared communicating badge is provided for transmitting an infrared coded signal, such as a patient identification number. The badge includes a sealed housing having an infrared transparent segment. The badge housing contains a power source, a microprocessor, an infrared transmitter, and an infrared receiver. The badge receiver is desensitized such that it does not respond to ambient light from the surroundings and, preferably, only detects signals from a programmer. This programmer transmits a coded infrared signal, which represents the patient identification number, to the badge. After the coded infrared signal is transmitted and stored in the badge, the infrared signal is transmitted periodically to another infrared receiver, located in a remote location. The remote receiver relays the information to a base unit at which the location of a person may be monitored.

Abstract: A control system is disclosed to extend the range of rotation of a radio-controlled servo towards its physical limits. A microprocessor and its various interconnections are inserted between the output of a radio control receiver and the input to the servomotor to analyze the output of the receiver and to re-scale it to allow movement beyond 45 degrees in either direction from its quiescent position. As described, this is done by converting the receiver output pulse from one which is 1 to 2 milliseconds in width to an output pulse for the servo which is 0.5 to 2.5 milliseconds in width.

Abstract: The disclosure relates to a system for the detection of human presence in hazardous situations near moving machinery; appropriately shaped electrodes are placed in an area to be safeguarded and a radio-frequency signal of appropriate frequency and voltage is applied on the electrodes creating an alternating electric field around them. A bridge circuit is used to measure the capacitive impedance created by the electrodes and a dissipation factor is calculated from the real and imaginary parts of the impedance. If a foreign object is introduced into the electric field, the characteristics of the dielectric are modified creating a change of the value of the dissipation factor. The dissipation of energy in the high frequency region is much greater if this foreign object is a biological tissue as compared to other types of materials, such as conductors or insulators.

Abstract: An electronic bubble level display is provided for determining surface normality when coupled with three sensors (18, 20, 22) sensing distance to the surface. The signals from the sensors are provided to an electronic processor (34) for computing the surface angularity and translating the angularity to specific positions on an LED dot matrix display chip (38).
