Systems and methods are provided for monitoring one or more patients to ensure compliance with required hygienic procedures and / or to ensure only authorized persons are allowed to attend to such patients. One system includes detectors that may be sequentially activated as a person approaches a patient. Activation of the detectors, in sequence, causes a signal to be transmitted by a controller. If the person is wearing a monitor and has complied with the required hygienic procedure, the monitor transmits a responsive signal to the controller that is encoded to indicate such compliance. If the person is either not wearing a monitor or the monitor does not transmit an appropriate responsive signal, the controller can provide a warning signal and cause a violation of protocol to be recorded. The system may include a portable sanitizer that is capable of functioning as a monitor. The systems and methods do not, however, require monitors worn by health care workers or other persons. Sensors may be associated with a hospital bed and / or a patient.

A method of synchronizing data transmission between a host computer system and a transmitter across an interface with variable delay or latency. The host computer system marks transition frames between successive transmission intervals and transfers the outgoing frames across the variable interface to the transmitter. The transmitter enqueues outgoing frames into one or more FIFO transmission queue(s) and processes the enqueued frames as appropriate for the communication protocol in use. Marked frames are detected as they reach the head of the appropriate transmit queue. In particular, while bypassing is not active, the transmitter transmits unmarked frames until the end of the current interval, or until there is insufficient time in the interval to transmit another frame or until a marked frame is detected. While bypassing is not active, the transmitter terminates transmission from the transmit queue when a marked frame is detected during each interval. While bypassing is active, the transmitter discards unmarked frames without transmission until a marked frame is detected. During each interval, the transmitter activates bypassing if a marked frame has not been detected and deactivates bypassing if a marked frame is detected while bypassing is active. The transmitter enables queue mark operation if a marked frame is detected while queue mark operation is not enabled. The transmitter increments a bypass counter each time an interval ends without detecting a marked frame, and disables queue mark operation if the bypass counter reaches a predefined limit.

A basic life support system (BLSS) includes a processing element and an output element, such as a display screen or an audio output element, for providing an individual with real-time instructions on providing emergency medical care to a patient until paramedics or other healthcare professionals arrive to take over care for the patient.

A frame-based communications system with selectable retry strategy including a controller that programs a retry strategy field of a frame descriptor of a frame, where the retry value indicates a selected one of a normal retry count, an alternative retry count, and at least one "no retry" option. The system includes a transceiver that attempts retransmission of the frame up to as many times indicated by a selected retry count or until expiration of a frame transmit duration, or that does not attempt retransmission if the retry value indicates no retry. The no retry options may include treating the first attempt as successful or returning an unsuccessful attempt as a failure. The frame itself may be programmed with a request to not acknowledge a successfully received frame to recapture the time normally allocated to acknowledgement frames. The transceiver may include acknowledgement logic that is configured to suppress an acknowledgement frame.

A communications system including a scheduling entity and a transceiver coupled across a variable timing interface. The scheduling entity forwards frames for transmission and identifies selected frames as persistent. The transceiver includes a queue, a frame manager and a transmission scheduler. The frame manager receives and enqueues forwarded frames and the transmission scheduler dequeues and transmits frames from the queue and forwards persistent frames back to the frame manager. The transmission scheduler includes persistence logic that detects a persistent mark and asserts a persistent signal that is detected by the transmission scheduler. The scheduling entity identifies a persistent frame by setting a bit in a transmit control field of the frame descriptor. The scheduling entity sends a clear persistence command to the transceiver to clear a persistent mark of an identified frame. The transceiver may be configured for wireless communications.

System and method for securely backing up and reliably retrieving vault data in a metering system that includes a host processor operatively coupled to a vault. Whenever a transaction is completed by the vault, the vault cryptographically signs the vault data, including ascending register, descending register and piece count and sends the cryptographically signed vault data to the host processor where it is stored in a data file assigned to the vault. Each storage of the cryptographically signed vault data is indexed to create a historical log of vault transactions. If the vault is lost or damaged so that vault data cannot be retrieved from the vault, the cryptographically signed vault data is retrieved from the host processor data file and verified.

A pair of through-holes 41a and 41b having the same shape are formed and aligned in a flexible board 4 on which a wiring pattern 42 is formed. A piezoelectric actuator 3 made of a piezoelectric bi-morph device is inserted into the first through-hole 41a and then into the second through-hole 41b from the opposite surface side. As a result, both the ends in the longitudinal direction of the piezoelectric actuator 3 contact the same surface of the flexible board 4. The flexible board 4 is disposed so that it contacts a touch sensor portion except for a part of the flexible board 4. Thus, a high performance force sense feedback function caused by the panel that deforms corresponding to an input operation can be accomplished at low cost.

A method for transmitting a data packet from a mobile node to a correspondent node through a foreign agent while maintaining security is disclosed. A correspondent node transmits a first data packet for communication with a mobile node to the home agent. Upon receipt of the first data packet from the home agent, the foreign agent transmits the first data packet to the mobile node through a radio channel. The home agent transmits the IP address of the foreign agent to the correspondent node after transmitting the first data packet to the foreign agent. The correspondent node transmits tunneling indication information indicating whether it can decapsulate a data packet encapsulated by the foreign agent to the foreign agent after receiving the IP address of the foreign agent from the home agent. The foreign agent encapsulates subsequent data packets received from the mobile node with a tunneling IP header for reverse tunneling and transmits the encapsulated data packets to the correspondent node, after receiving the tunneling indication information from the correspondent node.
