A secure video camera device for reducing the risk of visual and audio eavesdropping has a video camera and an electromechanical shutter behind a transparent cover in a secured enclosure. The shutter optically obscures the camera lens when the device is in secure state. A visual indicator indicates when the device is in operational state. A switch controllable by the user, select the state of the device by concurrently disabling the camera turning off the visual indicator in a secure state; and setting said device in an operational state by concurrently enabling the camera and turning on said lighted indicator. The device has a built in, or auxiliary microphone, and audio outputs which are disabled in secure state of the device. The device is tempered proof by an anti-tempering circuitry.

A medical training apparatus comprises a frame defining a work space simulating a body cavity and having an access opening to allow introduction of a medical instrument to the working space from externally of the working space. A sensor platform is rotationally mounted in the working space for rotating the platform to select angular positions for performing a series of simulated medical procedures. A plurality of modules are mounted around a perimeter of the platform. Each module comprises a different model upon which an associated medical procedure can be performed with a medical instrument. A plurality of sensors are each operatively associated with one of the modules for sensing progress of the associated medical procedure. A control unit is coupled to the sensors for monitoring progress of the medical procedures and providing an indication of status of the medical procedures.

User activity settings and other settings such as sound and vibration settings of applications that run on mobile devices are automatically adjusted. In one example, the mobile device includes a processor configured to adjust a user activity setting automatically according to an activity being carried out by a user. The activity of the user is determined by detected changes such as changes in the location or movement of the mobile device. The user activity setting can be associated with an application such as an instant messaging (IM) application stored in the memory of the mobile device.

A system and method for monitoring biological parameters that allows a user to wirelessly monitor one or more biological parameters of one or more individuals, either continuously or periodically is disclosed. The system may send an alert when the biological parameter exceeds a predetermined threshold, and also provides information to the user about selected individuals or about components of the system.

Barcode imaging and laser scanning systems are disclosed having at least one processor storing barcode decoding algorithms each corresponding to a respective symbology. The at least one processor causes at least one LED and/or a projected laser beam of the barcode imaging system to blink by rapidly turning it off and on one time or several times whenever a successful decode occurs. In the laser scanning system, the at least one processor causes a projected laser beam to be blinked by turning a laser beam system off and on one time or several times whenever a successful decode occurs. The act of blinking the at least one LED and/or the projected laser beam in the barcode imaging system or the act of blinking the projected laser beam in the laser scanning system provides a visual indication to a user of a successful decode. The act of blinking can also be used to visually indicate other information to a user. The act of blinking can be replaced by the act of changing the brightness of the at least one LED and/or projected laser beam in the barcode scanning systems.

A live circuit battery tester allows for determining the condition of batteries under load without disconnecting the batteries and a battery charger from the load or in any way disrupting system operation during the test. Battery testing is prevented when the batteries are being used in an emergency or if they are recharging from a recent discharge. The battery tester is under microcomputer control and incorporates automatic-self diagnostics and provides a visual indication if the batteries are good or if a specific problem is detected such as if the batteries are missing, have open cells, are sulfated or are in imminent danger of failure. The battery tester determines if the charger is operating properly and tests for an open cell, bad battery connection, sulfated battery, and a weak battery and provides a visual indication of any of these problems as well as an indication of a properly operating battery.

The invention relates to a coupling for tubular elements, with at least one plug and one socket, which plug can be inserted into the socket and can be locked therein, and both the plug and the socket have, extending approximately along their longitudinal axis, a channel for a fluid, said channel being arranged in such a way that the fluid can flow through the coupling in a locked state thereof. The plug can be locked in the socket in at least two locking positions, and the socket and/or the plug has at least one opening such that, in a first locking position, the opening connects the channel for a fluid to the environment, and, in a second locking position, the channel for a fluid is isolated from the environment. The invention relates further to a cannula that comprises such a coupling.

A switch power supply having active power factor correction is provided, including a power factor correction (PFC) circuit, a filter circuit, a main power stage, a first capacitor (C1) and an indicating circuit. An alternating-current input (IN) is connected to the first capacitor through the PFC circuit and is connected to the filter circuit through the indicating circuit. The indicating circuit consists of a light emitting diode (LED) having unidirectional conductivity and an inductor (L); and the current direction of power supplied from the PFC circuit to the main power stage through the inductor is opposite to the conduction direction of the LED. The LED may also be a light emitter of a photocoupler. The filter circuit at least comprises an electrolytic capacitor (C2). When the electrolytic capacitor is normal, an exciting current of the main power stage basically does not appear in the inductor and the LED does not emit light. When the equivalent series resistance (ESR) of the electrolytic capacitor sharply rises, the exciting current appears in the inductor. When a power transistor in the main power stage is switched off, the exciting current in the inductor cannot be abruptly changed; instead, the exciting current passes through the LED for freewheeling and enables the LED to emit light, thereby notifying a user or a circuit that the electrolytic capacitor may have the risk of failure. The switch power supply has low additional cost and unchanged efficiency and is easy to implement.

A refrigerated transport system (20) comprises: a body (22) enclosing a refrigerated compartment. A refrigeration system (30) comprises: a charge of refrigerant; a compressor (36) for driving the refrigerant along a refrigerant flowpath (34); a first heat exchanger (38) along the refrigerant flowpath and positioned to reject heat to an external environment in a cooling mode; and a second heat exchanger (42) along the refrigerant flowpath and positioned to absorb heat from the refrigerated compartment in the cooling mode. The refrigerated transport system has a detector (232) for detecting leakage of the refrigerant.

A table saw such as a chop saw, a miter saw, compound miter saw or a sliding compound miter saw that is provided with a laser arbor alignment system. An opaque shield or transparent shield having an opaque mask blocks the laser beam from being projected into a range of normal operator eye positions. One or more openings in the shield or opaque mask provide a sight line on a workpiece initially. As the saw is moved into engagement with the workpiece, the shield is pivoted away from the workpiece and a solid laser line is projected on the workpiece.

A medical device having an indicator to indicate whether the medical device has a waterproof seal enclosing an interior volume. The medical device includes a housing having an indicator formed on the exterior surface of the housing. The indicator is capable of moving from a first position to a second position, where the first position indicates that the medical device housing has a waterproof seal to prevent ingress of water into the interior volume of the medical device and the second position indicates that there is a leak in the housing.
