  • Publication number: 20210186384
    Abstract: A method for operating a medical device includes activating a processor in the medical device in a low-power operating mode, measuring a first voltage level of the battery, applying at least one discharge pulse to the battery in response to the first voltage level of the battery being greater than a predetermined passivation minimum voltage threshold and less than a predetermined passivation maximum voltage threshold, measuring a second voltage level of the battery after the at least one discharge pulse, and operating the processor in the medical device in an increased-power operating mode to continue operation of the medical device only in response to the second voltage level being greater than or equal to a predetermined operating voltage threshold, the predetermined operating voltage threshold being greater than the predetermined passivation minimum voltage threshold and less than or equal to the predetermined passivation maximum voltage threshold.

  • Publication number: 20200049691
    Abstract: According to some embodiments of the present disclosure, a device and method for determining an allowable amount of blood glucose (bG) of a patient is disclosed. The method further includes receiving a current bG measurement, determining a target bG value, and determining a correction delta bG value based on one or more advice history records. The method includes determining a correction meal rise value and determining a maximum allowed bG value based on the target bG value, the correction delta bG value, and the correction meal rise value. The method includes setting the allowable amount of bG value equal to the maximum allowed bG value when the current bG measurement is greater than the target bG value and determining the allowable amount of bG value using the target bG value and the correction delta bG value when the current bG measurement is less than the target bG value.

  • Patent number: 8775877
    Abstract: A method of checking the integrity of a dynamic link library (DLL) file called by an application being executed on a handheld medical device is described. The method includes loading a DLL from a read only memory (ROM) to a random access memory (RAM) beginning at a fixed location in the RAM. The DLL includes a first routine for performing a safety critical function of the handheld medical device and a second routine for performing a cyclical redundancy check (CRC) once the DLL is loaded to the RAM. The method includes selectively executing the first routine from the RAM. The method includes selectively executing the second routine from the RAM including: calculating a check value based on the DLL; comparing the check value with a predetermined check value; and indicating that an error is present when the check value is different than the predetermined check value.

  • Patent number: 4513278
    Abstract: A digital video display system wherein the various characters to be displayed are displayed in the form of images of the complete character rather than the standard dot-matrix pattern of the prior art. A character generator in the display system stores signals representing the various characters to be displayed which are retrieved from storage in response to a character code. The signals are in the form of a binary code having a sufficient number of bits to represent a different number of levels of gray-scale or luminance values for the various picture elements making up the character image. The binary codes thus retrieved from storage are supplied to a video synthesizer that generates the video signal to display the character images which may be displayed in a number of different modes including white-on-black, black-on-white, black-on-gray, and white-on-gray as well as different combinations of such modes to represent a cursor.

  • Patent number: 4332027
    Abstract: This disclosure relates to a station for a data transmission network which is adapted to operate in a cyclic mode for contending for access to the network channel along with other stations of the network. The three states of the cycle are the idle state, the packet-being-transmitted state and the acknowlegement period state. Each station will not begin transmission until it determines that the channel is in an idle state. Once the station has determined that the channel is idle, it will then delay for a period of time that is randomly chosen and, if the channel is still idle, will then begin transmission. In this way, contention conflicts between stations is minimized without unduly restricting communication between stations. Following transmission, the channel will again be quiescent a short period of time before the acknowledgement signal is transmitted from the receiver.

  • Patent number: 4284988
    Abstract: This disclosure relates to a digital video display system wherein a control element is provided that includes position and count registers to specify the initial position of a scan line and the number of scan lines displayed which registers are supplied with incoming data to specify the position of each character line so that the position of a character image on display can be adjusted upwardly or downwardly to give the appearance of smooth scrolling.The various characters to be displayed are displayed in the form of images of the complete character rather than the standard dot-matrix pattern of the prior art. A character generator in the display system stores signals representing the various characters to be displayed which are retrieved from storage in response to a character code. The signals are in the form of a binary code having a sufficient number of bits to represent a different number of levels of gray-scale or luminance values for the various picture elements making up the character image.

  • Patent number: 4156277
    Abstract: An I/O data interface provides an access mechanism without requiring additional lines on the bus for device address presentation for the request of access. Each peripheral device can detect an invitation-to-request access signal and in response thereto, to supply its own device address on the bus in a serial manner with any other device requesting access. Respective device addresses are assigned to respective peripheral devices in accordance with their priority, the higher priority devices having a higher address and the lower priority devices having a lower address. If any address bit of a particular device is lower than an address bit on the bus, the device ceases to supply its address bits with the result that only the requesting device having the larger device address will be selected for communication over the I/O bus.
