Abstract:
A device connected between a source of power and at least one load for selectively providing power from the source of power to the at least one load to operate in an area responsive to an environmental condition in the area. In one embodiment, the device includes a home mode, an away mode, and a custom mode, and a user interface for selecting one of the home mode and the custom mode to be operated. The device further includes at least one timer for timing a plurality of predefined operations, a first detector for generating a low light detection signal responsive to an ambient light level being below a predetermined threshold value, a second detector for generating a motion signal responsive to detection of a movement in the area, a dimmer for adjusting power supplying to the at least one load at a predetermined level, and a microcontroller coupled to the first detector and the second detector and coupled with the user interface for operatively controlling transmission of the source of power to the at least one load.
Abstract:
In some embodiments, a wall-mountable, programmable controller (2) having control keys (e.g., less than eight keys or another small number of keys), a subassembly including circuitry, and a control key insert (4) removably mountable to the subassembly and including at least one of the control keys. The controller can have first and second key sets (6, 8, 10) in distinct regions of the controller's surface and programmable switches that are actuatable by pressing control keys (20, 24, 30) in the key sets. At least one switch actuatable by pressing a key of the first key set (20) is programmed to perform a control operation of a first type (e.g., a power control operation), at least one switch actuatable by pressing a key of the second key set (24) is programmed to perform a control operation of a second type (e.g., a source selection operation), no switch actuatable by pressing a key of the first key set is programmed to perform a control operation of the second type, and no switch actuatable by pressing a key of the second key set is programmed to perform a control operation of the first type. In some embodiments, the controller is configured to control a projector.
Abstract:
According to the invention, an electrical domestic power installation system with a serial installation bus for the decentralised indoor switching, control, transfer and/or monitoring of energy and/or information which is simple to operate and install and also simple to configure can be achieved, whereby the system has a number of modular single modules, each of which has a logic module (6) with an application specific circuit (ASIC) and an EEPROM in the form of a chipcard (7) on which the parameter set for the individual single module is stored, such that on plugging in the chipcard (7) (the chipcard is electronically connected to the ASIC) the single module is fully configured.
Abstract:
To simplify the reconfiguration of switches in a building automation switch panel, touch switches (27) of the mechanical, capacitive or charge transfer type are configured so that the electrode pattern (25) on the switch body can be activated using switch positions on a cover plate (27). The electrode pattern on the reverse face of the cover plate are selected so that a set of cover plates in combination with a single switch body provides as many switch positions as the body can provide. This makes reconfiguring, a matter of changing the front cover plate of the switch and using a software program to reconfigure the electronics if necessary.
Abstract:
A system for controlling a plurality of ophthalmic microsurgical instruments is disclosed. Particularly, an endo-illuminator system (1000) for such ophthalmic systems is described for illuminating a posterior portion of a patient's eye during ophthalmic surgery. The novel endo-illuminator system (1000) includes a lamp system (1004), providing a high color temperature light which is shieleded for use with plastic lamp connections without melting.
Abstract:

Abstract:
This invention relates to a method and apparatus for executing secondary functions on an electrical switchgear device. In particular, the present invention relates to a method and apparatus which is implemented in the processing electronics of an electrical switchgear device which has a primary trip or protection function and also the capability to execute secondary functions or applications, such as over/undervoltage conditions and near fault warning levels and display. These secondary functions or applications being user configurable and are subject to processing availability and the constraints of the primary protection function.

Abstract:
A system for controlling a plurality of ophthalmic microsurgical instruments is disclosed. Particularly, the present invention includes a handpiece (1810) for activating a surgical instrument (i.e., such as scissors) connected to the handpiece. The handpiece (1810) includes a housing (1812) and a linear activator (1836) operatively retained within the housing. A nosepiece (1814) is mounted to one end of the housing and is adapted for correction of a linearly actuated surgical instrument. The nosepiece (1814) is fixed to the linear activator (1836) in a preselected calibrated position relative to the longitudinal axis of the linear actuator.
