There is described a method of acquiring physiological data with a wearable physiological data acquirer positioned onto an upper body of a user. The method generally has: acquiring first physiological data with the wearable physiological acquirer worn on the upper body of the user; removing the wearable physiological data acquirer from the upper body of the user; docking the wearable the physiological data acquirer to a docking station using a wired connection; the docking station extracting the first physiological data from the wearable physiological data acquirer via the wired connection; un-docking the wearable physiological data acquirer from the docking station after the extracting; repositioning the wearable physiological acquirer onto the upper body of the user; and acquiring a second physiological data with the wearable physiological acquirer worn on the upper body of the user.

A multi-parameter patient monitoring device rack can dock a plurality of patient monitor modules and can communicate with a separate display unit. A signal processing unit can be incorporated into the device rack. A graphics processing unit can be attached to the display unit. The device rack and the graphic display unit can have improved heat dissipation and drip-proof features. The multi-parameter patient monitoring device rack can provide interchangeability and versatility to a multi-parameter patient monitoring system by allowing use of different display units and monitoring of different combinations of parameters. A dual-use patient monitor module can have its own display unit configured for displaying one or more parameters when used as a stand-alone device, and can be docked into the device rack when a handle on the module is folded down.

A docking system for electrosurgical equipment where a first docking interface is a recess in the housing of a smoke evacuator and a second docking interface is a raised portion of an electrosurgical unit. The first and second docking interfaces have corresponding ground, power, and communication contacts, so that the two devices can be physically and electrically interconnected by mating the first docking interface with the second docking interface. The first docking interface is on the top of the smoke evacuator and the second docking interface is on the bottom of the electrosurgical unit so that the devices may be stacked and interconnected using a minimum amount of space without the need for cabling.

Methods, computer systems, and computer readable media are provided for promoting positive activity patterns for users and facilitate long-term adherence to the activity patterns, such as by providing alerts or electronic reminders to ambulate in a fashion that is responsive to an individual's actual activity patterns and behaviors and compatible with routine activities in the workplace and home. In particular, embodiments of the present invention are directed to measuring physical activity patterns during the waking hours of a human, and in some embodiments continuously measuring these activity patterns; automatically ascertaining whether the patterns exhibit sufficient frequency and variability of activity such as confers certain health benefits; and if the patterns do not manifest such features, to adaptively provide sensible reminders at irregular within-day intervals such as are likely to establish healthy patterns of ambulation and other light activity.

An electronic apparatus of a bio-signal measurement system comprises a first electric connector arrangement that is repeatedly connectable with and releasable from a first electric counter-connector arrangement of the bio-signal data processing apparatus. The electronic apparatus comprises also a second electric connector arrangement that is connectable with a second electric counter-connector arrangement of the bio-signal electrode arrangement in a releasable manner, and a battery that provides electric power for operation of the bio-signal data processing apparatus in response to an electric connection through the first electric connector arrangement between the electronic apparatus and the bio-signal data processing apparatus. The first electric connector arrangement comprises separate electric connectors, each of the connectors with a plurality of pins, the pins of the at least two separate electric connectors being for electric power supply and data transfer. The separate electric connectors of the first electric connector arrangement and their counter-connectors of the bio-signal data processing apparatus have structural shapes matched with each other for attaching them together based on contact friction in the releasable manner.
