Abstract: This disclosure relates to medical tubing installation detection. In certain aspects, a method is performed by a data processing apparatus. The method includes detecting that a tube is incorrectly installed on a drug delivery device by providing an instruction for a motor of the drug delivery device to pump a drug and receiving, after a period of time has passed since providing the instruction for the motor of the drug delivery device to pump the drug, a signal from a fluid detector connected to the tube, the signal indicating an absence of fluid in the tube.

Abstract: This disclosure relates to detecting fluid in medical tubing. In certain aspects, a method is performed by a data processing apparatus. The method includes controlling repetitive activation of the ultrasonic transmitter. The method also includes receiving a signal from the ultrasonic receiver during an activation of the ultrasonic transmitter. The method also includes determining that fluid is absent or present in a portion of the medical fluid tube based on a comparison between the signal and a threshold value.

Abstract: A communication system includes a voice-directed portable terminal with a voice user interface that is configured for being able to communicate with a computer system. The communication system includes a peripheral device having a cord coupled with the portable terminal and a connector adapted to disconnect from the portable terminal when a sufficient force is applied to the cord. This disengages the peripheral device from the portable terminal. The ability of the cord to break-away from the portable terminal prevents damage not only to the connector, but also to the cord, peripheral, and terminal.

Abstract: This disclosure generally relates to dialysis systems and related methods. In one aspect of the invention, a dialysis system includes a device configured so that a medical fluid can pass therethrough, and the device is adapted to remove one or more substances from the medical fluid as the medical fluid passes through the device. The dialysis system can also include a sodium control system adapted to alter a sodium concentration of the medical fluid.

Abstract: A communication system comprises a terminal configured for being able to communicate with a computer and to operate according to at least one operational parameter. A peripheral device for use with the terminal has a characterizing parameter associated therewith. The terminal is operable for reading the characterizing parameter from the peripheral device when the device is coupled to the terminal. The terminal is further operable for configuring itself to operate according to an operational parameter associated with the characterizing parameter of the peripheral device.

Abstract: A headset assembly includes a moisture-proof and temperature resistant headset module. The headset module is sealed against moisture and is constructed from materials that are durable and can withstand constant use, physical abuse, and rapid swings in temperature and other environmental conditions. Furthermore, the headset module is interchangeable with a variety of headset frames so as to provide comfort during prolonged use and in high ambient noise environments.

Abstract: A wearable, mobile and/or portable terminal for use in an inventory management system. The terminal includes a terminal housing, a battery pack removably receivable within an external battery-receiving cavity of the terminal housing, and a battery latching mechanism that secures the battery pack in the battery-receiving cavity in a latched condition. The battery pack has an unlatched condition in which the battery latch mechanism is disengaged from the battery pack. A camming surface of the battery latching mechanism lifts the unlatched battery pack from the battery-receiving cavity to promote its removal from the terminal housing. The terminal housing is sealed relative to the environment surrounding the wearable terminal battery pack and yet permits electrical coupling between the battery pack and the terminal in the latched condition.

Abstract: An electrical connector has a plug portion and a terminal portion. The plug portion is couplable to the terminal portion to provide an electrical connection between a device and a peripheral item which is securely coupled to the device during normal operation of the device. Advantageously, the plug portion will break-away from the terminal portion when a force applied to the plug portion reaches a specified magnitude to thereby prevent damage to the connector and to prevent hindering operation of the device.
