Abstract: Module adaptable to communicate with a suitable handheld devices or PDAs. Suitable devices include, but are not limited to, the Apple iPhone® or iPod®, Research in Motion Blackberry® smart phones, Motorola Droid smart phones, and Palm Pre smart phones. The module can be used without adding to the cost of the handheld device. This allows direct reimbursement for the replaceable meter module portion if payers choose to limit coverage for the full system, as well as the possibility of reimbursement for the entire system including the handheld device. Other solutions build the cost into the phone, which must be replaced to upgrade or replace the glucose function. Moreover, information from the glucose meter reading can be communicated from the PDA to a remote station for reporting the results. With an iPod-like approach, this could be accomplished without the need for a cellular signal or carrier, as long as a WiFi internet connection is available anywhere in the world.

Abstract: There is provided an energy delivery device comprising a storage device, a discharge circuit and a disarm circuit. The discharge circuit comprises a switch electrically connected to the storage device, and is selectively operable to deliver energy from the storage device to a load, e.g., a patient needing defibrillation, preferably in a multiphasic waveform. The disarm circuit comprises the switch. Preferably, the discharge circuit comprises an H-bridge circuit. There are also provided delivery devices: which comprise a shoot-through elimination circuit; which include housing elements which, when assembled, cause electrical connection between respective components; which include a housing having a small volume and an energy storage device having a large capacitance; which comprise a shunt circuit which, when activated, prevents switching of a switch. There are also provided methods of assembly and disassembly of an energy delivery unit and methods of delivering energy to a load.

Abstract: A method for calibrating an analysis instrument, e.g., a gas chromatograph, for water analysis that includes four steps. The first step is to continuously remove water from a liquid that contains water to produce a liquid containing a reduced amount of water such as by membrane pervaporation. The second step is to analyze the liquid containing a reduced amount of water for water by a reference water analysis method such as by Karl Fischer titration. The third step is to analyze the stream of liquid containing a reduced amount of water using the instrument to be calibrated, e.g., a gas chromatograph having a helium photoionization pulse discharge detector. The fourth step is to calibrate the instrument using the analysis of the second step. In a related embodiment, a system for normal phase chromatography.
