Abstract: The present application is concerned with a solid slow release pharmaceutical dosage unit. More specifically, the invention is directed to a tablet form prepared by direct compression of cross-linked amylose (CLA) having a definite cross-linking degree, .alpha.-amylase and a pharmaceutical agent. The presence of the cross-linked amylose allows a sustained release of the drug, while the .alpha.-amylase permits the modulation of the release time. In other words, the release time of the drug is function of the amount of .alpha.-amylase in the tablet. The amount of amylase is defined in terms of Enzyme Units.

Abstract: An overcap for a self-pressurized aerosol container is disclosed that dispenses the contents of the container as an aerosol spray in either an intermittent or continuous manner. The overcap is particularly useful in conjunction with the delivery of a fine particle size insecticide spray or fog and is economical to manufacture because it has few moving parts. The overcap comprises a shell containing an aerosol actuator button that further contain mutually cooperable, releasably locking engagement means. Intermittent aerosol dispensing is achieved without interference by the engagement means. Continuous aerosol dispensing is achieved by having the user position a movable engagement means so that it engages the other engagement means while the actuator button is held by the user in its dispensing position. The user then releases the actuator button and the engagement means retain the actuator button in the atomization position for continuous spraying. The second engagement means may be released to stop the continuous spray simply by again pressing the actuator button.

Abstract: A transmitter (107) includes amplifying circuitry (203) and control circuitry (215, 217, 219) for biasing the amplifying circuitry (203) so that it operates closer to saturation with increased efficiency. The gate voltage signal (213), which provides a gate bias, is coupled to the amplifying circuitry (203) and is dynamically varied by the processor circuitry (219) in response to the value of the amplifier control voltage (211) coupled to the amplifying circuitry (203). The amplifier control voltage (211), which has a value for maintaining the output power of the amplifying circuitry (203) at a constant, is produced by the integrating circuitry (217) in response to a comparison of the detected power output signal (216) produced by the detecting circuitry (215) and the power output control signal (218) produced by the processor circuitry (219). Efficiency is realized by dynamically varying the gate voltage signal (213) to its largest magnitude so that the amplifying circuitry (203) may operate as close to saturation as possible while still maintaining a constant output power.

Abstract: A method and material for shrink wrapping articles includes wrapping the article with a shrink wrapping material having a shrink/stretch film outer layer (12) and an inner layer of a non-woven fabric (14). The shrink/stretch film responds to heat by shrinking around the article being wrapped, while the non-woven material aerates to form bubbles (16) thus acting as a cushion between the shrink/stretch film outer layer and the article being wrapped. According to one embodiment of the invention, the article being wrapped is completed enveloped by the material, such as by forming the material into a bag encapsulating the article and then heating the bag to shrink the material into engagement with the article. According to another embodiment of the invention, material is made into a tape by applying an adhesive to the surface of the non-woven fabric which contacts the article being wrapped. The adhesive may either be a pressure sensitive adhesive or a hot melt heat activated adhesive. If a pressure responsive adhesive is used, the film may be a common film instead of a shrink/stretch film, and the adhesive is activated by pressing the material against the article. If a hot melt heat responsive adhesive is used, the material is heated to both shrink the film, thereby causing the non-woven to bubble up and act as a cushion between the film and the article and simultaneously to actuate the adhesive thereby causing the material to adhere to the article being wrapped.

Title: Variable rate signal transmission in a spread spectrum communication system using coset coding
Inventor: ZEHAVI EPHRAIM
IPC: H04J13/00
Filed: 1994-11-01
Granted: 2007-07-31
Abstract: An improved system and method for communicating information at variable data rates over in-phase (I) and quadrature phase (Q) communication channels in a CDMA spread spectrum communication system is disclosed herein. In an exemplary implementation an input information signal is transmitted over either an I or Q communication channel using a direct sequence spread spectrum communication signal. The information signal is initially divided into first and second subsignals, which are respectively provided to first and second coset-encoding networks. The first coset-encoding combines the first subsignal with a first coset code, while the second coset-encoding network combines the second subsignal with a second cosed code orthogonal to the first cosed code. In this way the first and second coset-encoding networks are operative to produce first and second coset-encoding signals, respectively. A composite coset-encoded signal formed from the first and second coset-encoded signals is then modulated by an orthogonal function signal to provide a first modulated signal. In-phase pseudorandom noise (PNI) and quadrature phase pseudorandom noise (PNQ) signals of predetermined PN codes are used for spreading the first modulated signal for transmission to a receiver over either the I or Q communication channel, respectively. The receiver is operative to produce an estimate of the input information signal on the basis of the modulated carrier signal received over either the I or Q communication channel.
