The present invention relates to a method and apparatus for programming a wireless handheld device and communicating between the handheld device and a programmer using inductive telemetry. The method may include the steps of activating a boot load mode of the handheld device, positioning the handheld device in proximity to a programming device, and downloading firmware to the handheld device from the programming device using inductive telemetry. The apparatus may include an inductive coil for inductive telemetry and a memory. The inductive coil is configured to be activated in response to inductive signals from an inductive coil of the programmer, thereby providing communication between the handheld device and the programmer. Communication between the handheld device and the programmer may include downloading firmware to the handheld device, and storing the downloaded firmware in the memory.

A portable source medical device determines communication links of a network presently available to effect communications with a target component when the source medical device is at each of a multiplicity of geographical locations. A profile is generated comprising information about each available communication link and attributes associated with each available communication link for each geographical location. When the source medical device is at a particular geographical location, a profile associated with the particular geographical location is accessed and a network connection is established between the source medical device and the target component using a communication link associated with the particular profile. Medical information is transferred between the source medical device and the target component via the communication link associated with the particular profile.
摘要:
A portable housing supports a processor coupled to memory for storing medical firmware and wireless radio firmware, first and second radios, a processor, and a power source. Communications are effected between an implantable medical device and the first radio in accordance with program instructions of the medical firmware, and between the second radio and the wireless network in accordance with program instructions of the wireless radio firmware. The first and second radios are configured to operate cooperatively in a first testing configuration, by which the first radio operates as a transmitter and the second radio operates as a receiver, and cooperatively in a second testing configuration, by which the second radio operates as a transmitter and the first radio operates as a receiver. Functional testing of the first and second radios is implemented using one or both of the first and second testing configurations.
摘要:
A modular portable patient communicator (PPC) provides for communications with a patient implantable medical device (PIMD) and connectivity with a central authority (CA) via an unsecured network. Medical firmware and a radio facilitate wireless interrogation of the PIMD and acquisition of PIMD data. A universal communications port facilitates mechanical and signal connectivity with one or a multiplicity of disparate detachable modules, some of which provide the PPC with an external communications facility and have disparate communication protocols. The PPC is devoid of an external communications facility other than the radio and universal communications port. Life critical network software is executed in cooperation with an attached module to cause the PPC to transmit a request to a network access facility for a connection to the unsecured network, authenticate the PPC to the CA, and facilitate secured communication between the PPC and CA upon successful PPC authentication.

A portable patient communicator (PPC) includes a portable housing that supports a processor coupled to memory for storing medical firmware and wireless radio firmware, first and second radios, a processor, and a power source. Communications between a patient implantable medical device (PIMD) and the first radio of the PPC are effected in accordance with program instructions of the medical firmware, and communications between the second radio of the PPC and the wireless network are effected in accordance with program instructions of the wireless radio firmware. Data from the PIMD is received via the first radio to which a priority level is assigned, such as in a tiered manner. A data transport mechanism is selected among disparate data transport mechanisms based at least in part on the priority level. PIMD data is transmitted to the wireless network using the selected transport mechanism via the second radio.

摘要:
A structure and method for electrically isolating a universal serial bus (USB) communication link is provided. One aspect of this disclosure relates to a system for isolating a host from a peripheral. The system includes a first programmable logic device for selectively passing two host USB lines into four host unidirectional lines. Four optoisolators are connected to the first programmable device via the four host unidirectional lines. A second programmable logic device for selectively passing four peripheral unidirectional lines into two peripheral USB lines is connected to the four optoisolators via the four peripheral unidirectional lines. The first and second programmable logic devices detect arriving edge transitions to determine whether a signal is arriving from a host or a peripheral, and disable and enable corresponding input and output lines to maintain unidirectional flow of the signal through the four optoisolators. Other aspects and embodiments are provided herein.
摘要:
A system for communicating with an implantable medical device via RF telemetry is disclosed which mitigates the effects of nulls caused by, e.g., multi-path distortion. In one embodiment, signals transmitted by the implantable device to an external device are simultaneously received with a pair of separate spaced apart first and second antennas. The antennas may provide spatial and/or polar diversity. The presence of nulls in the implantable device's transmission pattern can be determined by detecting an error rate in the signals received from the implantable device with each antenna.
