Abstract: A system and method related for performing lookup operations for objects distributed among different nodes in a peer-to-peer network are disclosed. Various nodes in the peer-to-peer network may store objects. Objects stored on a given node may be accessed by other nodes in the peer-to-peer network. To access an object, a node may first perform a lookup operation to determine where the object is stored, i.e., to determine which node in the peer-to-peer network stores the object. The peer-to-peer network may utilize a method to improve the performance of object lookup operations. In one embodiment, the method may allow object lookup operations to be performed with a latency on the order of one hop.

Abstract: A system includes a strap made using a layer of resilient and pliant material such as neoprene. A cutout extends along the strap and ends at connecting areas of the resilient and pliant material, and a load can be connected to the connecting areas. When a user employs the system, a weight of the load is primarily applied to the user at a load bearing area of the strap including the cutout. In some embodiments, the strap may further include a curved edge that helps the strap conform to anatomy (e.g., a shoulder) of a user, and a swivel that connects the strap to extension straps.

Abstract: A system for carrying a mobile device such as a camera includes: a cap with a shank; a module rotatably mounted on the shank; and a strap connection fixture on the rotatable module.

Abstract: Systems and methods for process flow tracking are presented. In one embodiment, a flow method comprises collecting records associated with flow for post analysis; performing a flow connection process associated with the flow, wherein the flow connection process examines information in a hash table and connects flow segments based upon connect ID; and performing a presentation process in which the flow is visualized, searched and traversed. In one exemplary implementation, a flow connection process utilizes a hash table that draws a correlation between the connect ID and a connect-start record or a connect-end record.

Abstract: An efficient distributed transaction protocol for a distributed file sharing system is described. One embodiment of the protocol involves a transaction coordinator node sending three messages to participant nodes, where the participant nodes reply to only two of those messages. In one embodiment, the transaction coordinator node may return success to the client application after receiving replies to the second message from the participant nodes. The protocol may provide benefits associated with traditional three-phase commit (3PC) protocols while also decreasing response time latencies experienced by client applications and decreasing network traffic.

Abstract: Inertia switches in insulating housings are used to make or break electrical contact. The switches may be small in size, and may be used with flashing light systems in footwear or other articles. One embodiment is a directional switch sensitive to the orientation of the switch and the motion of the switch due to outside forces. Footwear with flashing light systems that use these inertia switches may make the wearer or user more visible at night, adding a measure of safety as well as fun. Flashing light systems using these inertia switches may also be used to illuminate personal accessories and articles of clothing.

Abstract: A method and apparatus for illuminating lighting elements in one or more predetermined patterns. A preferred frequency controlled lighting system implementing this method includes a motion switch, a controller, a sound generator, and lighting elements. The motion switch creates an activation signal in response to movement of the motion switch, which is detected by the controller. In response to the properties of the activation signal, the controller illuminates the lighting elements in one or more predetermined patterns, or the controller actuates the sound generator to generate sound. Preferably, the lighting system utilizes at least two integrated circuits where a first integrated circuit functions as the controller and a second integrated circuit, having a higher cutoff operating voltage than the first integrated circuit, functions as the sound generator.

Flashing light systems are necessarily compact, consisting primarily of flashing lights and a power-and-control circuit that controls and enables the flashing of the lights. The lights may be illuminated by differing voltage levels, so that lights will flash brighter or dimmer depending on whether the light receives a higher voltage or a lower voltage. The voltages may be achieved by using batteries in series. A unique flashing effect is achieved by the use of differing voltages in sequence on the same lamps or LEDs. A battery charger may also be included to restore battery life.
