摘要:
An advancement mechanism of a lancing device operates to sequentially advance lancets in a cartridge. The advancement mechanism includes a rotary drive gear assembly with a first gear and a second gear that co-rotate in a first angular direction by operation of an inter-gear unidirectional drive mechanism such as a ratcheting mechanism. A second-gear unidirectional lock mechanism, such as a ratcheting mechanism, locks the second drive gear from co-rotating with the first drive gear in a second opposite angular direction without impeding rotation in the first direction. The second gear directly or indirectly rotationally drives a pinion gear, which rotationally drives a cartridge gear to advance the lancets in indexed increments for use. The first drive gear is rotated in the first and second directions by a rack gear of a translating operating handle. In addition, a rotary-gear cap-displacement mechanism and a rotary-gear charging/actuation mechanism are provided in other embodiments.

A lancing device and lancet are provided with depth-control, lancet ejection, and/or guidance mechanisms. The depth-control mechanism includes a dial rotationally mounted at a distal end of the housing of the lancing device, the dial being coupled to a linkage whereby rotation of the dial imparts translational movement to a stop surface of the linkage to limit the stroke of the lancet and thereby control lancing penetration depth. The ejection mechanism includes an ejector that is advanced into contact with a transversely flared flange of the lancet to discharge the lancet from the lancing device. The guidance mechanism includes an inner guidance housing for restricting out-of-axis movement of a lancet carrier.

A device and method to test a circuit in a chip that has memory embedded in the chip using a scan chain. This device and method generates a known signal simultaneously to a bypass circuit and the memory onboard the chip. The bypass circuit uses a series of exclusive OR gates, a flip-flop, and a multiplexer to receive the known signal. The exclusive OR gates reduce the number of signals input so that they match the number of signals output by memory. A flip-flop is used to store the data received from the exclusive OR gates and transfer it to a multiplexer. The multiplexer receives data from memory and the flip-flop and selects which data to pass on in the circuit. When a scan test is being run on the circuit the multiplexer passes on only the data from the flip-flop. When a scan test is not being run the multiplexer only passes on the data from memory. This device and method allows for circuits to be tested using a scan chain that could not otherwise be tested due to the presence of memory embedded in the chip.
摘要:
A method performed by a processor of a electronic device, including rendering (402), on an electronic display, a line segment having a first direction and moving in a second direction. The method also includes a step of determining (404) whether the direction of the line segment (the first direction) is in the same direction that the line segment is moving (the second direction). If the processor determines that the line segment is not moving in the same direction of the direction of the line segment (the first direction), then the processor performs (408) a first action, such as adjusting the color intensity of the line segment. If the processor determines that the line segment is moving in the same direction of the direction of the line segment (e.g., the two directions are substantially parallel to each other), then the processor performs (406) a second action.

Disclosed are methods for consistent navigation among higher-level and lower-level windows on a device's display screen. A user can consistently navigate from one higher-level window to another and use the same navigation tools to navigate among the lower-level windows (if any) within a higher-level window. Some embodiments present a set of small “overviews” to the user. Each overview corresponds to one of the higher-level windows. In addition to the set of overviews, a larger “preview” can be shown of the window with focus. If the window with focus contains lower-level windows, then the preview can include “snapshots” of those lower-level windows. In some embodiments, a “title bar” provides more information about the window with focus, such as the title of that window. When a lower-level window is currently active within the higher-level window with focus, the title bar can show information about that active lower-level window.
摘要:
A system for determining whether a memory is connected to a controller in a node of a data network. In order to utilize non-volatile memory elsewhere in the system, it is possible to eliminate the EEPROM which is normally connected to the controller. In order to indicate that the EEPROM is deliberately missing, a pull-up resistor connected to a voltage source is connected to the chip select signal line which normally runs between the controller and the EEPROM. If a high signal is received, the controller knows that the EEPROM is deliberately missing and that non-volatile memory will be provided elsewhere in the system.

A method and apparatus for non-contiguous translation protection table that includes one or more first registers, two or more second registers, an address translator, and a detector. Each first register contains a value denoting a size of each of two or more blocks of memory. Each second register contains a value denoting the starting physical address of an associated one of the two or more blocks of memory. The address translator receives a virtual address and translates the virtual address to a physical address of one of the two or more blocks of memory. The detector detects whether the received virtual address is outside of the range of the two or more blocks of memory. The blocks of memory may be translation protection tables that reside in physically non-contiguous memory locations.

Improved lancet configurations and protective lancet endcap configurations are disclosed. In example forms, one or more flexing cantilevers project from the lancet body for coupling with a cooperating receiver of a lancing device. A gripping handle extends from a sterility cap for ease of removal from and replacement over the lancet tip. A lancet body has a smoothly curved wave contour with at least one crest and at least one trough for engagement with a cooperating receiver of a lancing device.
摘要:
A device and method to test memory embedded in a chip in which the memory is not directly accessible from a tester external to the chip. The device and method uses a state machine embedded in control circuitry of the chip to execute software to test the memory embedded on the chip. The software in turn employs a row and column address generator connected to the state machine to access each memory location in the memory embedded in the chip. A data generator is also used by the software to generate and write data to memory locations specified by the row and column address generator. Several multiplexers are used to accept data from the data generator and pass the data to the memory embedded in the chip. These multiplexers act to enable reads and writes to memory when a memory test is performed or to enable normal reads and writes to memory when normal operations of the chip are executed. A data comparator is used to determine if the memory is working properly.
