A sliding door latch system and method is disclosed herein. The sliding door latch system is used to prevent movement of a sliding door between a closed position and an open position relative to a fixed door frame. The device may be installed as a secondary safety latch on a sliding door having a primary latch that is located at an elevation within the reach of the child. The device may be installed at an elevation above the reach of the child, but readily within the reach of an adult user. The sliding door latch includes a latch arm located outside the sliding door to simplify installation. The latch arm is user-locatable in a latched position, a momentarily released position, and a held-in-release position.

A domestic electrical appliance, in particular a dishwashing machine, includes a main appliance body having a product treatment chamber, a door mounted on the main appliance body so as to be pivotable about a horizontal pivot axis close to the floor for closing an access opening to the product treatment chamber and a locking device having a locking assembly arranged on the main appliance body and a closing pin arranged on the door. The locking assembly has a latch movable between a release position and a latching position where the latch engages behind the closing pin to hold the door closed and releases the closing pin to open the door. The latch performs a rotational movement along a horizontal plane as it moves between the release position and the latching position, the closing pin being oriented vertically when the door is closed.

A door locking device (1) including a support body (6) which can be fixed to a door (5) of an electric household appliance, a bracket (7) which can be fixed to a structural element (3) of the electric household appliance and a latching device (8) including: a locking tooth (10) constrained to rotate and translate relatively to the support body and which can be coupled with a first end thereof (12) with a transversal element (11) of the bracket; a sliding stem (13) cooperating with a second end (14) of the locking tooth by means of conjugated cam profiles (15, 16) carried by the locking tooth and by a head (17) of the stem; a compression spring (18) associated with the stem for thrusting the cam profiles (15, 16) into contact; and a tilting element (19) hinged to the support body to cooperate with the transversal element (11) of the bracket independently of the locking tooth, to activate a microswitch (23) when the tooth is in a locking position, wherein it engages the transversal element (11) of the bracket.

Aspects of a symmetric coherent optical mixer are described. In one example, the coherent optical mixer includes a group of symmetric MMI couplers and a group of symmetric bend waveguides optically coupled between the MMI couplers. The group of symmetric MMI couplers can include an input for a local light reference signal, an input for a modulated light signal, and outputs for detection of data from the modulated light signal. The group of symmetric MMI couplers can include four MMI couplers, each of which comprises a 22 MMI coupler of symmetric dimension. The group of symmetric bend waveguides can include a symmetric layout of four 90 bend waveguides optically coupled between the four MMI couplers. The coherent optical mixer, which can be implemented as a Silicon Photonics (SiPh) device, provides better performance as a 90 degree optical hybrid than prior mixer devices due to its symmetric layout.

A locking apparatus for a rollup door, comprising a striker member, latch assembly including a latch, a release lever, a trigger, a cam and a solenoid. The latch assembly may also include a limit switch for detecting when the latch assembly is in an unlocked position. The locking apparatus can be electronically unlocked or it can be unlocked manually by a user by actuating the solenoid which causes the latch to release the locked striker member.

A multi-function latch and latch bolt includes a pair of mechanical fastener to be installed on a gate for the purpose of holding the gate in closed position, and that a person standing on the inside of the fence can disengage the latch hook bracket from the latch bolt, or disengage the latch bolt from the latch hook bracket in any of which method to unlatch and open the gate from inside the fence even when the outside of the latch is locked. On the other hand, when the latch is not locked on the inside but locked on the outside with an incorporated lock, keyed or combination padlock; then a person standing on the outside of the gate may open the gate if he/she has an appropriate key or knows the combination codes in order to unlock, unlatch and open the gate from outside the fence.

A lock for a closure element of a real estate property, includes a pivoting catch on which a spring acts in a preferred direction, a locking member, and a manual or mechanical drive device. The locking member is designed as a rotary locking member that is driven by the drive device in a circulating manner about a locking member axis in only one rotational direction and comprises multiple locking elements which are offset to one another over the angle at the circumference of the locking member and which interact with the pivoting catch as respective tumblers depending on the rotational angle. Only one of the locking elements constantly acts directly on the pivoting catch for a locking and unlocking process, and the adjacent locking element opposite the rotational direction of the rotary locking member acts on the pivoting catch by rotating the rotary locking member for a subsequent locking and unlocking process.

A latch or connector system having a latch housing, a first latching component, a second latching component, and a handle. The first and second latching components are movably mounted to the latch housing, and movable respective latched and unlatched positions. The handle is movably mounted to the latch housing and operatively associated with the first latching component and the second latching component. The handle is movable from a closed handle position to an open handle position to cause the first latching component and the second latching component to move from their respective latched positions to their respective unlatched positions, and the handle is movable from the open handle position to the closed handle position only when the first latching component and the second latching component are in their respective latched positions.
