International Business Machines Corporation - Armonk NY

International Classification:

H03M 7/30

US Classification:

341107, 341 51

Abstract:

Disclosed is a method for constructing Slepian-Wolf codes, wherein the designed Slepian-Wolf codes are robust to mismatched decoding. The disclosed method for constructing Slepian-Wolf codes includes the steps of: choosing representative probability distributions from a set of possible probability distributions; choosing a probability distribution as a decoding metric; converting the chosen decoding metric to a cyclic-symmetric channel; computing the initial message value given the cyclic-symmetric channel; computing a set of probability distributions of the initial message given the initial message values and the representative probability distributions; optimizing the degree distribution given the set of probability distributions of the initial message; optimizing the decoding metric.

International Classification:

US Classification:

3406362, 3406361, 340603, 3405731, 600365

Abstract:

A system and method is described for rapid charging and power management of a battery for a meter. A charger component is operably associated with the meter and is capable of executing a rapid charge algorithm for a rechargeable battery. The algorithm includes monitoring for a connection to an external power source and implementing a charging routine of a battery at a first charge rate and then at a second charge rate. The second charge rate is lower than the first charge rate. A temperature rise in the rechargeable battery due to the first charge rate has a negligible heat transfer effect on the fluid sample. The meter can also include a power switch for controlling current flow to a battery fuel gauge. The power switch is open when the meter enters into a sleep mode. The state of battery charge is determined after the meter exits the sleep mode.

International Classification:

G06Q 10/00

US Classification:

705 3, 705 2

Abstract:

A device for managing health data provides a first housing portion including a data storage system that stores health data and a second housing portion including a data communications element. The data communications element provides data communications between the data storage system and a processing device that processes the health data according to a data-management software. The first housing portion and the second housing portion are connected by a cable that communicates signals between the data communications element and other components in the first housing portion. Another device for managing health data provides a first housing portion including a health data management system and a data communications element that provides data communications between the health data management system and an external processing device. The second housing portion is removably coupled to the first housing portion, and includes at least one component used by the health data management system.

International Classification:

G06F 15/00

US Classification:

702130, 3406362, 3405731, 340603

Abstract:

A system for a meter configured to determine an analyte concentration of a fluid sample includes a housing and a temperature sensor disposed within the housing. The system also includes a processor configured to receive temperature data from the temperature sensor upon the meter entering one of a charge state and a discharge state. The processor is further configured to predict a temperature value that approximates the ambient temperature outside of the housing. The predicted temperature value is based on historical temperature data received from the temperature sensor such that the predicted temperature value remains constant if a recently received temperature value remains within predetermined upper and lower temperature thresholds and the recently received temperature value exceeds the at least one predicted temperature value.

Abstract:

Premature vascular senescence is reversed or prevented in tissue or cells by contacting the tissue or cells with a peroxynitrite scavenger or peroxynitrite formation inhibitor that does not diminish nitric oxide synthesis. This finds application in treatment of patients with a disorder associated with elevated levels of advanced glycation end products in blood or tissue, e.g., patients with end stage renal disease or poorly controlled diabetes, and in contacting vascular tissue or cells ex vivo to prevent occurrence of premature senescence.
