  • Patent number: 11957465
    Abstract: Apparatuses, methods, and systems are disclosed for accelerated ergonomic collection of capillary blood. An apparatus and system include a blood collection module with a proximal portion including a vacuum generation chamber, a distal portion including a blood collection chamber, a concave mid portion including a pressure equalization channel configured to equalize reduced air pressure. The apparatus further includes a sealing surface to stably seal the blood collection module to the skin around a collection site and a slide latch actuated by a lengthwise sliding motion. Also included is a lancet carrier with linearly-arranged lancet strips to puncture rows of blood extraction slits in the collection site. The apparatus also includes an angled transfer port with a low-resistance non-microfluidic blood flow channel to a transfer module, then to a plasma separation module with a multilayer laminate and plasma separation membrane. Methods for accelerated ergonomic collection of capillary blood are disclosed.

  • Publication number: 20070135855
    Abstract: A patient management device for portably interfacing with a plurality of implantable medical devices and method thereof is presented. Permission to interrogate one or more implantable medical devices is authenticated. Patient device data is individually exchanged through interrogation of at least one authenticated implantable medical device through short range telemetry. External device data is exchanged via communication with at least one external device through long range telemetry. At least one of the patient device and external device data is maintained contemporaneously to execution of operations to perform one or more of relay, processing, and outputting of the patient device and external device data subsequent to the interrogation of the implantable medical device.

  • Patent number: 7110814
    Abstract: An improved protection mechanism to protect from unintended execution of critical tasks operates, in one example embodiment, by receiving a request to start a task by a first process. The first process informs a second process of running an algorithm to verify the legitimacy of the received request to determine the need to start the task. The second process stores the information regarding the starting the algorithm by the first process. The first process runs the algorithm to verify the legitimacy of the received request, and conveys an outcome of the verification to the second process. The second process enables the start of the task by the first process based on the outcome of the verification and a checking of the stored information and the first process starts the task.

  • Patent number: 5677618
    Abstract: A DC-to-DC switching power supply (12) receives a DC biased power signal at a first input (14), a control signal at its control input (16) and produces an output DC voltage at its output terminal (20). A power supply controller (30) compares the produced output signal V.sub.out with an input reference signal V.sub.ref. The reference signal is an analog signal which may be produced via digital-to-analog converter (34) which converts a digital input command into a corresponding analog signal V.sub.ref. The resulting error signal is then passed through a proportional gain block 36 and an integral gain block (38). A signal proportional to the differential of the output voltage is passed through a differential gain block (44). The outputs from the proportional gain block (36) integrator gain block (38) differential gain block (44) are summed in the second summer (40) and applied as the input to a delta-sigma converter (42).
