Abstract:
A pressure-responsive B-surface seat occupancy sensor unit for detecting an occupancy state of a seat comprises a pressure sensor arranged on a base plate. The pressure sensor includes a printed circuit board having a first surface with at least two electrodes and a second surface, with which the PCB is arranged on the base plate, and a membrane element arranged in facing relationship with and spaced from the electrodes so as to deflect under pressure and establish an electrical contact between the electrodes. The base plate includes one or more fixation elements, by means of which the base plate is fixable to the structural frame, the seat cushion and/or the cushion-supporting springs of the seat.
Abstract:
Die Erfindung betrifft ein Anlasserrelais (10) eines Kraftfahrzeugs mit einem Gehäuse (13), welches mit darin angeordneten Geräteelementen versehen ist und zumindest eine Öffnung (24) zur Belüftung aufweist, dadurch gekennzeichnet, dass in der zumindest einen Öffnung (24) ein Druckausgleichselement (25) angeordnet ist.
Abstract:
This invention relates generally to patient monitoring systems and more particularly concerns devices and systems used to monitor bed patients in hospital or other care-giving environments. In accordance with a first aspect of the instant invention, there is provided a pressure sensitive mat which has been completely sealed around its exterior edges. The interior of the mat is kept in communication with the atmosphere by way of a section of flexible tubing which encloses the attached electrical line. One end of the tubing is sealed inside of the mat and the other end is open to the atmosphere, thereby providing a passageway for air to reach the interior of the mat. This arrangement, however, protects the interior of the mat from exposure to fluids near the perimeter of the mat and allows the mat-portion of the invention to be completely submersed without adverse effect, if that should become necessary.

Abstract:
The present invention relates to a switch device (100) for use in hand-held power tools. The switch device (100) may include at least one chamber (102) whose interior serves as an accommodation space. The chamber (102) may partially encase an operational member (104) for actuating the hand-held power tool through the switch device (100). Further, the switch device (100) is provided with multiple holes (202) on side walls (204) of the chamber (102) to create a passageway for external particulate materials. Also, a bottom surface (205) of the chamber (102) may be sloped to extend from an interior of the chamber (102) to each of the multiple holes (202), to enhance the discharging of the external particulate materials through the holes (202).
Abstract:
A sealed electrical enclosure for use in hazardous locations for enclosing circuit breakers having a bottom housing and a top housing with a labyrinth joint, a serrated joint, or combination of both being formed therebetween, a first aperture extending through a first end wall of the bottom housing and positioned adjacent a first contact terminal of a first circuit breaker, the first aperture further including a first metal bus extending therethrough and in electrical contact with the first contact terminal, and a second aperture extending through a second end wall of the bottom housing and positioned adjacent a second contact terminal of the first circuit breaker, the second aperture further including a second metal bus extending therethrough and in electrical contact with the second contact terminal, and a first actuating mechanism positioned on the top housing adapted for manipulating a switch of the first circuit breaker.
Abstract:
An electrical component may include a vent located in a mounting portion of a case to vent a blast from within the case. A chassis may have a mounting site for an electrical component, wherein the mounting site includes a passage to receive a blast from the electrical component. A system may include a chassis having a mounting site to engage a mounting portion of a case for an electrical component, wherein the mounting portion of the case includes a vent, and the chassis forms at least a portion of a blast chamber to receive a blast from the vent.
Abstract:
The casing has a detachable projection (3) on one wall, into which a channel (33, 34) extends from the interior (11). The channel has at least two sections (33, 34) with different cross-sections which decrease stepwise toward the exterior. Ventilation openings of various sizes suitable for a variety of applications of the element can be obtained by detaching the projection at different places.

Abstract:
Switch element for use in a potentially explosive area A switch element, e.g. a relay, for use in a potentially explosive area has a base plate and a top (302), defining a cavity housing the switch contacts. The switch element also has an opening to the outside and is otherwise sealed to the outside. The opening spreads any escaping explosive energy that is released during an explosion within the switch element over a sufficiently long period of time such that the explosive energy escaping to the outside does not ignite the explosive mixture in the potentially explosive area. In prefered embodiments, the opening is a hole (305) covered by a grid (311) or mesh (312). Alternatively, the opening takes the form of a gap (105, 105') in the seam between the base plate (101) and the top (102) or takes the form of a hole (205) with a biconical or meandering form.
