An infrared sensitive electric controlled lamp seat serves to control the illumination of a bulb automatically. The infrared sensitive electric controlled lamp seat includes a lamp seat and an electric controlled device. The lamp seat is an power transferring case having a U shape cone-like shape, and the upper end thereof is installed with a conductive stud, while the lower end thereof is installed with a cone net bulb fixing case. The bottom of the bulb fixing case is installed with a conductive stud for locking the bulb. The electric controlled device is a circuit board. The center of the bottom is installed with an infrared sensing head. The circuit board is firmly secured to the bulb fixing case so that the infrared sensing head is exactly protected in the net case. The power transferring case serves to cover the upper portion of the bulb fixing case. Therefore, an infrared sensitive electric controlled lamp seat is formed. Thus, the present invention can be installed to another lamp seat for inserting a bulb so as to automatically sense and control the illumination of a bulb.

A modular patient care system is described having unique mechanical, electrical, and logical features. An apparatus is described for allowing a modular connection arrangement wherein modules are detachably connected to each other in a convenient, flexible, interchangeable, and secure manner by providing a hinge connector pair, a specially located latch mechanism, and a guide means between any pair of modules. Additionally, an apparatus and method is described for automatic, sequential, and dynamic logical address assignment of functional units attached to the central management unit, according to their respective position in a linear array of units. Logical address assignment is designed to occur automatically upon a physical reconfiguration of the functional units, without requiring external input or a rearranged scheme for determining the relative physical positions of the functional units.

An electrical connection and interlock circuit system (20) operates between a battery (14) and a drive motor (16) of a vehicle electric drive. Circuit system (20) includes a connection circuit (22) having first and second connectors (24) and (26) for energizing the drive motor (16) by the battery (14) and also includes an interlock circuit (28) that operates to electrically disconnect the connection circuit when either connector is in a partially connected position. The circuit system (20) also includes a power connector housing (46) at which the second connector (26) is located along with a third connector (66) that is connected to the drive motor (16), and a mechanical interlock (66) prevents disconnection of the third connector until after the second connector is disconnected so that there is no power at the third connector during its connection or disconnection.

An electrical receptacle is disclosed which deactivates the front of an electrical receptacle when an electrical plug is not present. The receptacle includes a semiconductor switch mounted between the hot contacts of the receptacle, and the hot conductor of an electrical power cable. The receptacle also includes a momentary contact switch located between the contacts of the ground receptacle portion, activated by the ground pin of an electrical plug upon engagement, and deactivated upon retraction of the electrical plug. The momentary contact switch, when activated, also activates the semiconductor switch which in turn, activates the receptacle front. A second embodiment of the invention further includes an optoelectronic switch in series between the momentary contact switch and the semiconductor switch which requires redundant activation of both switches for activation of the receptacle front, remotely activating the optoelectronic switch and local activation of the momentary contact switch by the electric plug.

An electrical outlet and safety control circuit for preventing accidental shock comprising a socket with a pair of outlet terminals isolated from a primary voltage source by normally opened relay contacts, and a switch actuatable by an elongated pin on the associated electrical plug upon insertion thereof into the socket, the switch being serially connected to the relay for closure thereof and simultaneous energization of the electrical terminals upon complete insertion of the plug.
摘要:
In a mating plug and socket assembly one prong of the plug has a light and photocell associated with it when it is in place in the socket so that light is transmitted to the photocell thereby indicating that the plug and socket are mated. This photocell controls a relay having contacts in series between the electrical source and the socket so as to only close the circuit to the socket when the plug and socket are so mated. There are various arrangements of the light and photocell in conjunction with the one prong and the socket.
