Abstract: A thin client resides on a personal data assistant (PDA) and provides functionality for Java applications being executed by a Java virtual machine (JVM) on the PDA. The thin client enhances the PDA's operating system (OS) and facilitates the selection and downloading from a server of Java applications, the exchange of data between applications executing on the PDA, the enablement of the PDA's drivers, peripherals, and software functional components for Java applications, synchronization of data between Java applications on the PDA and the server, security and encryption of data, and maintenance of a connection between the PDA and a server.

Abstract: The invention disclosed is a composition for improving cold tolerance in animals and humans, comprising an adenosine receptor antagonist or an adenosine de-activator. Preferably, a nutritional supplement is also provided which further enhances cold tolerance. The nutritional supplement includes various combinations and amounts of carbohydrate, protein and fat.

Abstract: A toy block constructed into one geometrically regular block formed from at least two nestingly interengagingly configured three-dimensional components having adjacent pairs of couplers interconnected by a generally H-shaped unitary hinge, the hinge having first and second opposing sides with an interconnecting web and a transversely extending plate portion. The sides are provided with axially aligned pairs of inwardly extending pivot stub projections. The plate portion includes a pair of oppositely extending, generally resilient, aligned catch arms with depending tangs which engage detents formed between the couplers for retaining the components in preferred position. The blocks may form humanoid objects, quadrupeds, or articles such as vehicles or furniture, or the like.

Abstract: An inertial phonograph device having a flywheel (50) carrying a record member (56) with a plurality of interleaved sound tracks pre-recorded to match the rundown speed of the flywheel (50). A constant predetermined rotational force is imparted to the flywheel (50) by means of a sector gear (82) selectively engaging a pinion (58) on the shaft (52) of the flywheel (50), the sector gear (82) being pivoted to its start position by the force of a spring (106). The sector gear (82) is pivoted against the force of the spring (106), out of engagement with the pinion (58), by means of a pull string (84) passing through a sector clutch (96), and, after engagement of the sector gear (82) with the pinion (58), rotation is restricted by a brake shoe (120) coacting with the flywheel (50) until the brake shoe (120) and sector gear (82) are released by the action of the pull string (84) and the sector clutch (96).
