International Classification:

G06F013/00

US Classification:

711115000

Abstract:

A memory cartridge is disclosed. In one embodiment, the memory cartridge has a housing, and a memory unit in the housing, where the memory unit stores a plurality of data sets. An edge connector is electrically coupled to the memory unit. A selector is coupled to the housing and the selector is adapted to select at least one of the data sets. A locking member for locking the selector is coupled to housing.

International Classification:

A61B 5/145
A61B 5/00

Abstract:

Apparatus and methods for blood analyte sensing, data processing, and transmission and storage. In one embodiment, the sensor comprises a spatially compact multi-element implantable blood glucose sensor apparatus which is configured to generate signals or data relating to sensed blood glucose levels of a host being, and process the data in vivo to generate e.g., data suitable for transmission to an external receiver device for storage and indication. The implanted sensor apparatus may also determine the need for an alert. In one variant, the sensor apparatus provides for ultra-low energy consumption through a number of coordinated mechanisms, including only issuing wireless transmissions (advertisements) when communication is needed, and use of multiple “layered” operating modes. Reduced energy consumption advantageously also extends implantation longevity and reliability/availability.

International Classification:

G05D 1/02
A47L 11/40

Abstract:

A robotic cleaning device and method of control thereof. The device and method enable multiple cleaning passes within an environment efficiently, cleaning the entire environment more than once, or cleaning the entire environment and then focusing on one or more particularly dirty areas to provide enhanced cleaning by making one or more passes over a dirty area in a dominant and a non-dominant direction. The robotic cleaning device may identify such areas in the course of its cleaning, or it may record such areas previously as being historically dirty and requiring additional attention. The device may vacuum; it may shampoo; it may polish; or it may perform other cleaning operations. Where the device is battery-powered, the device may check its state of charge before performing the enhanced cleaning, and may repeat the enhanced cleaning if the battery or batteries have sufficient charge.
