Abstract: Described herein is an implantable device comprising a radiation-sensitive element (such as a transistor) configured to modulate a current as a function of radiation exposure to the transistor; and an ultrasonic device comprising an ultrasonic transducer configured to emit an ultrasonic backscatter that encodes the radiation exposure to the transistor. Further described herein is an implantable device comprising a radiation-sensitive element (such as a diode) configured to generate an electrical signal upon encountering radiation; an integrated circuit configured to receive the electrical signal and modulate a current based on the received electrical signal; and an ultrasonic transducer configured to emit an ultrasonic backscatter based on the modulated current encoding information relating to the encountered radiation.

Abstract: Disclosed are methods of treating muscle loss in a subject comprising administering a therapeutically effective amount of a GHSR1a antagonist, a GHSR1a inverse agonist, a ghrelin antagonist, or a decoy ghrelin receptor to a subject in need thereof. Disclosed are methods of inhibiting the binding of ghrelin to GHSR1a (or GHSR1a to ghrelin) in a subject comprising administering a therapeutically effective amount of GHSR1a antagonist, GHSR1a inverse agonist, ghrelin antagonist, or decoy ghrelin receptor to a subject in need thereof. Also disclosed are methods of inhibiting the binding of ghrelin to GHSR1a (or GHSR1a to ghrelin) in a subject comprising mutating GHSR1a. Disclosed are methods of lowering proteasome activity in a subject comprising administering a therapeutically effective amount of a GHSR1a antagonist, a GHSR1a inverse agonist, a ghrelin antagonist, or a decoy ghrelin receptor to a subject in need thereof.

Abstract: In a transmitter circuit designed to operate over a specified transmit frequency range, information as to the specific frequency within the specified transmit frequency range at which the transmit up-converter of the transmitter circuit is to be operated, is used to generate a control signal for a high-power amplifier within the transmitter circuit, where the high-power amplifier automatically optimizes its operations based on the frequency indicated by the control signal. For example, for the transmitter circuit of a PCS base station transmitter, control signals received by the transmit up-converter from an alarm control board identify the particular 5-MHZ or 15-MHZ PCS frequency block for the base station transmitter. The up-converter uses that frequency information to generate a two-bit control signal identifying one of three 20-MHZ frequency sub-ranges within the 60-MHZ PCS forward-link transmit frequency range.

Abstract: The input impedance of a high-frequency monolithic integrated-circuit amplifier is modified to increase the maximum output power capability of the amplifier. This modification compensates for a reduction in output resistance at high frequencies caused by feedback capacitance coupling the output and input of the amplifier.

Abstract: A microwave balun is constructed by combining a four-transmission-line branch-line coupler with a single-transmission-line delay element. This construction results in a simplified, compact arrangement for combining first and second signals applied to respective first and second ports, phase shifted by 180.degree., and providing the combined signal at a third port. The balun is a reciprocal device and may be operated in reverse with a signal applied to the third port to obtain outputs at the first and second ports.

Abstract: A monolithic microwave buffer amplifier is adapted to increase its input impedance at microwave frequencies. Capacitive reactances in first and second stages of the buffer amplifier appear collectively at the input of the first stage as a negative resistance. Compensating positive resistance is electrically connected to the input of the first stage to cancel the negative resistance and provide a sufficiently high resistive input impedance.

Abstract: A drum lifter comprises a base including a pair of parallel spaced fork tubes adapted for receiving at one end and positioning over a pair of vertically adjustable forks of a lift truck. A support plate spans the other ends of the tubes and mounts thereover a transverse support pipe with spaced stops thereon. A pair of spaced sleeves are mounted upon the pipe between the stops, each sleeve having an upright jaw support plate secured thereto. A pair of laterally spaced opposed arcuate drum-engaging jaws project forwardly from the sleeves and are pivotally mounted upon the jaw support plates for rotation upon vertical axes. A stop plate is mounted on and extends laterally outward of each jaw and is engageable with the support plate when the jaws are in a horizontal position for holding the jaws to operatively clamp a drum therebetween.

Abstract: A drum lifter comprises a base including a pair of parallel spaced fork tubes adapted for receiving at one end and positioning over a pair of vertically adjustable forks of a fork lift truck, and a support plate spanning and secured to the other end of the tubes. An upright mount plate is secured to the support plate. An upright drum support plate is parallel to, arranged forwardly and pivotally mounted intermediate the ends upon the mount plate. First and second drum grips on the drum support plate are adapted to operatively engage the exterior of a drum to be lifted and transported. A forwardly extending latch link is pivotally supported upon the mount plate adjacent its upper end and pivotally mounts the drum support plate. A third drum grip depends from the forward end of the latch link and is adapted to retainingly engage over and against the interior of the drum.
