Abstract: A jewelry clasp with top and bottom sections, each section having a bore to receive a magnet, and each section having an interlocking surface on the perimeter of the bore. An eyelet is positioned on the perimeter of each section. The interlocking surfaces consist of mating camber protrusions that will lift and separate the top and bottom sections when the sections are rotated in one direction by the eyelets. One magnet is longer than the other to provide structural resistance to separation at the camber protrusions by opposing force exerted through the eyelets. In another embodiment, a steel tube is positioned in the bore of one section to encase the magnets to redirect magnetic flux and provide additional structural resistance against opposing force through the eyelets. Additional steel shielding can be used to reduce magnetic flux emanating from the clasp. Neodymium magnets coated with gold or silver are preferred.

Abstract: Method for manufacturing endodontic instruments having either helical or non-helical flutes with hard surfaces and resilient cutting edges by either an EDM or ECM process, wherein material is removed from the instrument blank in the desired flute pattern. The EDM or ECM process disintegrates the surface material, and as it cools, at least a portion of the removed material re-deposits onto the surface being machined to form a recast layer having a surface hardness that is at least about 15% greater than the hardness of the material forming the instrument blank.

Abstract: A method repacks variable width trace data into a different packet length previous to being stored into memory. In order to conserve bandwidth, the trace data may also be compressed during transmission by eliminating the transmission of packets that have the same value.

Abstract: A flux indicator is utilized as a low-overhead consistency check for a shared resource such as a data structure, and provides a mechanism for determining both whether a data structure has or is currently in the process of being modified. In connection with attempts to modify the data structure, the flux indicator is updated from a first state to a second state prior to modifying the data structure, and thereafter updated to a third state after modifying the data structure, Copies of the flux indicator are then obtained both before and after attempting to obtain a copy of data from the data structure. The validity of the copy of the data is ensured when the first copy of the flux indicator does not indicate that the data structure is in the progress of being modified and the first and second copies of the flux indicator have the same state.

Abstract: When a PROGRAM CODE FLUSH signal is generated in a target processor during a test procedure, a sync marker is generated in a program counter trace stream. The sync marker includes a plurality of packets, the packets identifying that the sync marker is has been generated as a result of the PROGRAM CODE FLUSH signal. The program code flush sync marker identifies the absolute program counter address at the time of the generation of the PROGRAM CODE FLUSH signal and relates the PROGRAM CODE FLUSH signal sync marker to a timing trace stream. The PROGRAM CODE FLUSH signal is generated at the transition between the program (primary) code instructions being removed from the pipeline flattener and the interrupt service routine (secondary) code instructions being removed from the pipeline flattener.

Abstract: A method is provided for synchronizing the playback of a digital audio broadcast on a plurality of network output devices by inserting a control track pulse in an audio stream of the digital audio broadcast. The method includes the steps of outputting a first control track pulse as part of an audio signal which has unique identifying characteristics and is regularly occurring, outputting a second control track pulse so that the time between the first and second control track pulses must be significantly greater than the latency between sending and receiving devices, and coordinating play of audio at the time of the occurrence of the transmission of the second control track pulse assuring the simultaneous output of the audio signal from multiple devices. The control track pulses have a value unique from any other portion of the audio stream. The digital audio broadcast from multiple receivers does not present to a listener any audible delay or echo effect.
