Abstract: A multi-level secure switch includes a security enforcer logic chip, a switch chip, a management processor, and a plurality of physical ports. The security enforcer logic chip is configured to receive and transmit a plurality of data packets, each having an associated security level. The switch chip is configured to transmit the data packets to and receive the data packets from the security enforcer logic chip. The management processor is configured to provide security parameters to the security enforcer logic chip. Each of the plurality of physical ports have an associated security threshold and transmit and receive data packets to and from the security enforcer logic chip. The security enforcer logic chip is configured to transmit a data packets to a physical port only when the security level associated with data packet is compatible with the security threshold associated with the physical ports.

Abstract: A gang-type lawn mower system comprises a main frame or frame structure and a plurality of mower decks secured to the main frame. Mounted on the main frame is a power source such as an internal combustion engine. A drive train is interconnected between the power source and each of the mower decks. Thus, each mower deck is driven by the single power source. Further, the frame structure includes a tongue that is adapted to be connected to a tractor. Therefore, in cutting grass, the frame structure is pulled over the ground and each of the mower decks, driven by the power source, cuts grass or other vegetation that passes under the mower decks. Additionally, each mower deck is pivotally connected to the frame structure about at least one pivot axis.

Abstract: Circuitry 400 remotely controls the power in a computing system. An infrared receiver 401 receives a code transmitted from a remote device 206; Circuitry 402 generates a pulse in response to the code, the pulse emulating an output of a switch 205. A transistor 403 has a control terminal for receiving the pulse and outputting a control signal in response.

Abstract: A waste disposal system for providing and removing a controlled flow of absorbent cat litter is disclosed. The apparatus comprises a hopper for receiving and storing the litter in a flowable form. The hopper is provided with an exit passage at its lower end and a measured container is disposed beneath the exit passage. A horizontal conveyor belt is positioned below the exit passage movable between a utility position beneath the passage and a discharged position to operably dump the litter. A holding drawer is disposed beneath the conveyor belt for receiving the used material.
