Patent CA-2215807-C (CA)
Inventor: FERNALD KENNETH WILSON
IPC: H03M1/20
Filed: 1996-03-28
Granted: 2000-10-17
Abstract: A method and apparatus is disclosed for use in an implantable device that includes an analog-to-digital converter (ADC) for converting electrograms (such as EKG signals) into digital codes that can be stored in memory. The ADC  constructed according to the present invention is capable of achieving considerable power savings by minimizing the number of clock cycles required to determine the correct digital code for a particular sample point on the electrogram signal, thus making it possible to turn off some or all of the ADC  logic during idle periods. The ADC includes prediction logic that provides a starting point for subsequent searching for the correct digital code value.  The prediction logic receives recent code conversions values which it uses to predict the current digital code value. This predicted digital code is converted to an analog value and compared with the actual electrogram voltage to determine if the prediction is above or below the correct code representation. Next, the ADC adds (or subtracts) a constant value (C) to (or from) the predicted code and compares the result to the actual electrogram voltage. If the ADC determines that the predicted value is within the constant value (C) of the correct digital code, then the ADC counts in the proper direction (determined by the first comparison) until the comparator changes output state, indicating that the correct code is found. If the ADC determines that the predicted value is not within the constant value (C) of the correct digital code, then the successive approximation logic is enabled and used to find the correct code. By selecting the constant value (C) to be approximately equal to the number of clock cycles required for the successive approximation circuitry to determine the correct code, the present invention, on average, can determine the correct code significantly faster than can be obtained using only successive approximation logic.

Abstract: Method for the regeneration of active carbon and polymeric adsorbents having oxidizable, organic pollutants adsorbed thereon by electrochemical and chemical means and apparatus therefor. The method involves a desorption step and a decomposition step. Desorption is accomplished in one embodiment by flowing an aqueous stream at a preselected pH through the adsorbent material. Generally, decomposition is accomplished by contacting an aqueous stream containing an organic pollutant with hydroxyl radicals. Sequential or simultaneous desorption and decomposition can also take place during electrolysis in an electrolytic cell. During decomposition the active carbon canbe made a carbon bed electrode of the cell. Electrolysis to produce peroxide can take place in the presence of a transition metal or a chelate of a transition metal while feeding an oxygen containing gas to the electrolysis cell.

Granted: 2002-06-04
Abstract: An apparatus and method for locking and unlocking mobile telecommunications handsets or other devices is disclosed. Each handset is unactivated at the time of purchase. Other than emergency calls, or account activation, no calls can be made using the handset unless it has been unlocked. The handset is capable of receiving a readable subscriber identity module (SIM) having a network (or other) ID and a codeword, and its operation is to be locked and unlocked with respect to the entity corresponding to the ID on the SIM. Futhermore, the handset includes a processor programmed witha unique equipment identification number and a key. All handsets manufactured as part of a particular batch may include the key, which is burned or otherwise written into a memory area of the handset so that it may not be read without its being destroyed. The handset processor is also programmed to produce a handset-specific key as a function of the equipment identification number and the batch-specific key. Upon activation of the handset, the customer service center associated with the network operator transmits a modifier to the handset. The handset changes its handset-specific key according to the modifier to yield an operator-specific key. The resulting operator-specific key is used in conjunction withthe network (or other) ID (from the SIM) to produce a checkword. If the checkword matches the codeword, which is read off the SIM, the handset is unlocked (i.e., enabled) for normal use. Other features of the invention include relocking the handset according to similar principles, and providing a personal identification number for permanently unlocking the device, so that it can be used with any compatible SIM.

Title: Method for loading a java application program
Inventor: HOLIDAY MATTHEW R JR
IPC: G06F9/445
Filed: 1999-11-19
Granted: 2003-09-16
Abstract: A method for loading software into a Java virtual machine ("JVM") in a manner suited for real-time server applications. The software to be loaded is organized by Java package and class so that an application may be loaded in units of packages. Each package, and each class within a package, is loaded into the JVM in an order such that no package or class is loaded before the packages or classes upon which it depends. All software for an application is loaded into the JVM, and any compilation, optimization, or initialization takes place, prior to execution of the application program, so that no delays are incurred during such execution. Software loaded into the JVM, as well as attributes of that software, are identified. Versions of packages are compared when loading the packages to ensure compatibility. An "image" of loaded software is created, which image may be reused by the JVM in order to restart an application rapidly following a failure. A loader environment within the JVM contains information about all loaded applications, packages, and classes, their attributes, and their interrelationships.
