H03K 706

US Classification:

375239, 37524002, 37524028, 329313

Abstract:

A radio frequency identification (RFID) tag device having a pulse position modulation (PPM) decoder circuit which calculates a relative frequency relationship between an internal clock-oscillator of the RFID tag device and an external PPM source such as a RFID tag reader, and then synchronizes the RFID tag device PPM decoder circuit to the required precision for reliable PPM symbol decoding. The PPM decoder is synchronized by measuring the âcounts per pulseâ (CPP) from a calibration cycle having a plurality of pulses in a single symbol frame.

International Classification:

US Classification:

711112, 707202, 707204

Abstract:

A system and a method for scheduling disk writes for use with an application server, transactional system, or other server. The disk scheduler and method is independent of the underlying operating system and the disk hardware. This allows it to be used without porting to the various settings in which application server might be deployed. In some embodiments, a high-performance, transactional filestore is also provided to minimize the latency of small, synchronous writes to disk. The implementation uses a log-structured file system combined with disk scheduling. By relaxing the requirement that log records be physically contiguous, every modification to the disk can be scheduled.

Abstract:

A system for high level dynamic hot code generation. A class file container object is first created. Methods and code are then added to the class file container object. Byte code is then generated from the populated class file container object. From the byte code, instances of the new class object can by generated. The program code generator is configured to generate code at a programming language construct level, thereby working at a level of program language statements, expressions, variables, and other constructs.

US Classification:

340/010200, 370/311000, 370/336000

Abstract:

Arbitration of multiple transponders, such as RFID tags, occurs in an interrogation field. The arbitration process is custom-tailored for individual applications, under software control, by the transponder reader or tag reader. Different wake-up slots are calculated for each tag during successive transmission cycles based upon the tag ID and the transmission cycle number. The tag reader may also send a special command to a tag to read its data and cause the tag to become decoupled from the environment. The tags may be selectively placed in either a tag-talk-first mode or a reader-talk-first mode. Furthermore, the tag reader may send a special fast read command to the tag which includes a read request and at least one parameter of the read request.

International Classification:

US Classification:

715762000, 717106000

Abstract:

A system and method for dynamically generating proxy classes in order to enforce call-by-value semantics between clients and EJBs collocated with a virtual machine. The virtual machine can be a Java virtual machine (JVM) or some other type of virtual machine. The proxy classes are dynamically generated at runtime using dynamic byte code generation. Generated proxies are then interposed between a client and an EJB. The interposition of the generated proxies allows the proxies to intercept communication between the client and the EJB. The dynamically generated wrapper classes may be used in any system wherein a first entity invokes a second entity, wherein the second entity has an interface that can be retrieved or introspected and utilizes call-by-value semantics.

International Classification:

H04Q 100

US Classification:

340 102

Abstract:

An RFID tag circuit provides magnetic decoupling and amplitude modulation. The circuit is made up of a first inductor and a second inductor connected in series, a first capacitor, a second capacitor, and a switch. The circuit includes a first resonant circuit formed from a parallel connection of the series connected first and second inductors, and the first capacitor. The first resonant circuit has a primary resonant frequency. The circuit also includes a second circuit formed from a series connection of the second capacitor and the switch. The series connection of the second capacitor and the switch are connected in parallel to the second inductor. One end of the series connected second capacitor and switch is connected to the common connection between the series connected first and second inductors. When the switch is open, the second circuit has a minimal or no effect on the tag and the first resonant circuit resonates at the primary resonant frequency when the tag is exposed to an external field at or near the primary resonant frequency. When the switch is closed, the second circuit defines a high impedance parallel resonant circuit which functions to block or minimize current flow at the primary resonant frequency, thereby preventing the tag from drawing any significant amount of power from the external field and from resonating at the primary resonant frequency.

International Classification:

US Classification:

Abstract:

A rotating field antenna is provided which includes a figure eight shape loop, a center loop magnetically coupled to the figure eight shape loop, and a drive element for driving the figure eight loop. The figure eight shape loop has an upper loop, a lower loop and a crossover region therebetween. The center loop overlaps at least a portion of the crossover region and at least a portion of one or both of the upper and lower loops. The center loop has no direct or physical electrical connection to the offset figure eight shape loop. Magnetic induction produces a 90-degree phase difference between the phase of the figure eight loop and the phase of the center loop. The antenna thereby produces a rotating composite field when driven by the drive element. The figure eight loop and the center loop are coplanar. The drive element may be an amplified voltage source which has a fundamental frequency of about 13.
