Abstract: An anti-polish ring for an internal combustion engine is provided. The anti-polish ring includes an axially extending ring portion that is configured to scrape a top portion of a piston in a cylinder liner. The anti-polish ring is configured to accommodate passage of an intake or exhaust valve thereby. The anti-polish ring may include an alignment feature so that the anti-polish ring is inserted in a predetermined orientation in the cylinder. The anti-polish ring may include a heat shield and/or a seating member.

Abstract: Controller for retrofit connection to a pre-installed door entry system of an area having a communal entrance secured by a communal door having a first electrically operated lock and a non-communal internal region secured by an internal door having a second electrically operated lock, the door entry system comprising a door panel associated with the communal entrance and an entry phone located within the internal region; the controller being connectable to existing circuitry of the entry phone to be able to receive a request for entry into the internal region from the door panel; and transmit an electrical signal to the entry phone to unlock the first and second electrically operated locks. The controller comprises a detector; a verifier; and a lock controller arranged to generate the signals to control the entry phone to unlock the first and second electrically operated locks when the right of access has been verified.

Abstract: A case for a tablet shaped device, the case including a body having a first face and a second face having a tablet shaped device receiving area; and a flap having a distal portion magnetically attracted to the body, and configurable between a first configuration in which the flap covers the tablet shaped device receiving area and the distal portion is wrapped around an edge of the body and contacts the first face such that the flap is secured by the magnetic attraction of the distal portion to the body, and a second configuration in which the flap is folded to form a stand secured by the magnetic attraction of the distal portion to the body.

Abstract: The present invention provides a multi-layered framing system for securing cladding to an exterior wall having exterior insulation. The framing system provides horizontal elements positioned across the exterior insulation, wherein the horizontal elements are secured to studs within the wall using fasteners. Vertical elements are secured to the horizontal elements. Then panels of cladding are secured to the vertical elements.

Abstract: The present invention provides a universal framing system for securing cladding to the interior or exterior of a structure. The framing system comprises hat channels, face plates, Z-channels, inside corner trims, outside corner trims, and window trims. The components of the framing system are secured to a wall of a structure, then panels of cladding are secured to the components.

Abstract: In a fixed delay optical communication system, rate adjustable differential phase shift key (DPSK) techniques eliminate the need for multiple comparing modules, each corresponding to a different data rate. Setting alternative data rates at integer multiples of the fundamental data rate of the optical communication system allows the system to process the respective integer number of symbols per period of the system, wherein the period of the system is the inverse of the fundamental data rate. Pulse carving techniques may be used to set the duty cycle of clock levels associated with a clock signal. The clock levels may be combined with respective symbols to provide optical symbols having a duty cycle less than 100%.

Abstract: A network is operated such that message forwarding traffic is shared among routers in a load-sharing set. The routers are respectively associated with different non-overlapping subspaces of a source address space from which source addresses of source nodes on the network are drawn, and each router has an identifier uniquely identifying the router in the load-sharing set. Address request messages identifying a predetermined forwarding route are broadcast on the network by source nodes, each request message containing a source address of the broadcasting node. In response to each address request message, each router determines whether the source address is within the address subspace associated with the router, and if so returns the router's identifier to the source node.
