Title: Apparatus controller, device and method for controlling data transmission of digital apparatus, and data transmission control system
Inventor: WAKAMORI MASAHIRO
IPC: H04N7/173
Filed: 1999-08-06
Abstract: An apparatus for controlling the operation of a plurality of digital devices connected to a network includes a transmitting/receiving processing unit (102) for transmitting/receiving data and control signals to and from the network, a time designation processing unit (104) for receiving a preset designation time from the system controller via the network, and a designation time detection processing unit (105) for comparing the preset designation time with the current time, and when the designation time agrees with the current time, the received data is switched over without interruption, and the switching is synchronized with the next I frame. The operation of the digital device is accurately controlled at predetermined timing without issuing an instruction packet. The amount of data to be transmitted may be set to an amount less than the maximum transmissible data to provide free time before starting transmission of the next data group.

IPC: H04M17/00
Filed: 2001-06-01
Abstract: The present invention relates to a system, a method and a service node for providing a pre-paid service to a mobile station for data transmission in a packet data cellular telecommunication network.      A connection is established between the mobile station and the service node in the packet data cellular telecommunication network. Upon establishment of the connection, at least one pre-paid connection limit parameter is obtained from a subscriber account database. The at least one pre-paid connection limit parameter is indicative of a limit at which the connection must be terminated. Then, the service node monitors the connection to determine whether the data transmission exceeds the at least one pre-paid connection limit parameter. If the data transmission exceeds the at least one pre-paid connection limit parameter, the connection is terminated.

Title: Method and apparatus for infusing liquids using a chemical reaction in an implanted infusion device
Inventor: MANN ALFRED E
IPC: A61M5/142
Filed: 2000-06-08
Abstract: Embodiments of implantable infusion pumps are provided that use a process of converting a first substance to a second gaseous substance (e.g. by electrolysis) to provide a motivating force to expel a desired fluid (e.g. drug or medication) from the pump into the body of a patient. An expandable sack may be provided around a gas producing electrolytic cell, such that as the gas expands it displaces a portion of the volume originally allocated to the desired fluid, and thereby forces the fluid from the pump. Pumps may be provided with a double septum to allow refilling of the desired fluid while simultaneously allowing removal of the generated gas from the system while using a single needle. Recharging of pump batteries may occur by direct electrical conduction through one or more needles and/or by r.f. energy transfer. Programming of the pump may occur by way of conductive paths provided by one or more needles or by means of r.f. transfer. A pressure regulator may be provided in vicinity to an outlet port of the pump so as to enable more reliable operation of the pump when subjected to changes in ambient pressure. A one-way valve may also be provided to reduce risk of back flow into the pump.

Title: Retainer system for vehicle soft tops and tonneau covers
Inventor: STEVENS MICHAEL C
IPC: B60J7/10
Filed: 2002-02-11
Abstract: A retainer system for vehicle soft tops and tonneau covers. The system includes a belt attached to the edge of the fabric of the top or tonneau cover and a channel member mounted on the vehicle to selectively receive the belt. The belt is provided with a stop mechanism to positively prevent the belt from peeling out of the retaining channel member farther than desired. In the preferred embodiments, the stop mechanism is a notch or cutout in the belt:  With the present retainer system, the notch will effectively stop the peel or withdrawal of the belt from the retaining channel at a predetermined location along the channel. In this manner, the belt and attached top or tonneau cover can be partially removed from engagement along the channel member to make it easier and quicker for the operator to perform a number of desirable tasks.

Patent CA-2376460-A1 (CA)
Inventor: POULOS STEVE
IPC: A62D3/00
Filed: 2002-03-06
Abstract: A Municipal Waste Gasification System whereby Municipal Solid Waste (MSW) and other forms of waste are converted to useful energy via a close coupled gasification process in an artfully designed Waste Conversion and Recycling Vessel (WCRV) that allows for precise control of the temperature and oxygen content of the batch waste charge while providing for the automatic sorting of all post-gasification residuals. Embodied in the present invention is a Key Accelerant Balancing System (KABS) that precisely controls the temperature in the range of 800-1100°F and oxygen concentration in the 5-7% range within the WCRV continuously for 12-14 hours yielding overall better efficiency of the conversion of the waste to gas and minimizes pollutants in the present invention. The concrete structure that supports the WCRV doubles as a thermal envelope from which hot air is drawn from to dry the incoming waste. The residual glass, aluminum and other metallic components of the waste are automatically sized and separated from the ash for recycling by a logic control system of gravity doors, vibrating super-magnetized grates, vacuuming, screening and eddy currents advantageously increasing the speed, safety and efficiency of the gasification and automatic recycling of unsorted MSW into energy and marketable raw materials. The gas produced in the waste conversion vessel is conditioned in a unique fuel preparation cell by mixing with ambient air or oxygen and can be used to fire the waste conversion vessel's heating elements with the excess gas or used to run a gas fired turbine or boiler to produce electricity with the residual heat used for district heating, or industrial processes.
