A compact fall detection sensor includes a case. A magnet is housed in the case. A reed switch with a pair of reeds are integrally positioned around the central axis of the case at the bottom of the case. In an upright state, the magnet is gravitationally positioned in the longitudinal direction of the reed switch around the central axis of the curved surface of the case, each magnetic pole magnetizing the corresponding reed of the reed switch, allowing one of the reeds to be magnetized to N pole and the other reed to S pole to turn on the switch. When inclined from the upright state, the magnet slides along the curved surface of the case and deviates from the central axis, to position only one of the magnetic poles of the magnet around the central axis to turn off the reed switch.

A blender transmits an electrical signal via a transparent film so as to detect whether a container lid is closed. The blender includes a container body receiving food; a main body provided under the container body and supporting the container body; a container lid mounted removably to the upper surface of the container body and configured to open/close the upper part of the container body; and a detection system configured to detect whether the container lid is mounted to the container body, wherein the detection system includes a transparent electrode film attached to the surface of the container body and guiding the flow of electricity. Accordingly, the transparent electrode film can transmit whether the container lid is mounted to the main body without spoiling the appearance of the container body made of a transparent material.

A magnet reed switch assembly. The magnetic reed switch assembly includes a reed switch having a body and a pair of electrical contacts disposed in the body. A ring magnet has a bore, and a portion of the body of the reed switch is disposed within the bore, with the ring magnet positioned close to the pair of electrical contacts. The ring magnet is movable along the axis of the body between a first position and a second position. A plunger includes a proximal end coupled to the ring magnet and a distal end having a sensing magnet. When a ferrous target is disposed near the sensing magnet, the plunger moves toward the ferrous target causing the ring magnet to move from the first position to the second position, and the reed switch to move from an open state to a closed state.

A rotation angle detection sensor detects the rotation angle of a rotating part attached to a structure including a fixed part and a rotating part that rotates around a rotary shaft. The rotation angle detection sensor includes a reed switch attached to the fixed or rotating part with reeds placed near the rotary shaft. An annular magnet is attached to the rotating or fixed part. A magnetic circuit is formed with respect to the reed switch, with its central axis arranged concentrically with the rotary shaft. When the magnet rotates around the central axis with respect to the reed switch, if the same poles of the magnet are lined up in the longitudinal direction of the reed switch, the reed switch is turned off. If opposite poles of the magnet are lined up in the longitudinal direction of the reed switch, the reed switch is turned on.

A safety switch includes an actuator that has a first possible actuator position and a second possible actuator position and a blocker that has a first possible blocker position and a second possible blocker position. The first possible blocker position overlaps with the second possible actuator position. The safety switch includes a device for generating an electrical signal representative of a current position of the actuator. When the actuator is in the first possible actuator position and the blocker is in the first possible blocker position, the blocker prevents movement of the actuator from the first possible actuator position to the second possible actuator position without first moving the blocker from the first possible blocker position to the second possible blocker position.

A trigger arrangement for a scanning system can include a sealed housing configured to support a scanning device, a trigger, and an actuation device configured to control functionality of the scanning device. A first magnet can be positioned outside of the sealed housing and can be configured to be selectively moved by the trigger. A second magnet configured to be repelled by the first magnet can be positioned inside of the sealed housing. A connecting member that supports the second magnet can be configured to transfer force from the second magnet to the actuation device. Some configurations can provide tactile feedback to a user when the trigger is used.

A portable object including a near-field communication device. The communication device includes an antenna, the ends of which are configured to be connected electrically to an electronic chip, forming, together with the chip, an electrical circuit. In an original manner, the portable object includes a control element which is able to be displaced between two predefined positions, i.e. an active position wherein the communication device is activated and a passive position wherein the communication device is deactivated. The portable object includes, furthermore, a mechanical switch which is able to switch between an open state and a closed state in response to a displacement of the control element from one to the other of its predefined positions.

A handheld wireless device for remotely activating a remote controlled system, the handheld wireless device comprising: a casing holding an electrical energy store and circuitry including a transponder arranged to transmit a wireless signal in response to a request received from the remote controlled system; the handheld wireless device further comprising a switching assembly comprising: an electrical switch connected between the electrical energy store and the circuitry, the electrical switch operable by an applied magnetic field to switch the circuitry including transponder on and off; and a mechanical actuator mounted to the casing, the mechanical actuator operable to move a magnet relative to the electrical switch to operate the electrical switch; the mechanical actuator and magnet being located outside the casing and the electrical switch being located inside the casing.

A magnet reed switch assembly. The magnetic reed switch assembly includes a reed switch having a body and a pair of electrical contacts disposed in the body. A ring magnet has a bore, and a portion of the body of the reed switch is disposed within the bore, with the ring magnet positioned close to the pair of electrical contacts. The ring magnet is movable along the axis of the body between a first position and a second position. A plunger includes a proximal end coupled to the ring magnet and a distal end having a sensing magnet. When a ferrous target is disposed near the sensing magnet, the plunger moves toward the ferrous target causing the ring magnet to move from the first position to the second position, and the reed switch to move from an open state to a closed state.

A relay is disclosed. In an embodiment a relay includes a magnet armature including a magnetic core and a permanent magnet secured to the magnet armature for identifying a position of the magnet armature.
