An in-camera two-stage compression implementation is described that reduces the latency between snapshots to a fraction of that otherwise required by other systems that either process complete compression following each snapshot or that incorporate heavy, bulky, and expensive RAM hardware capable of maintaining several raw luminosity records (unprocessed file containing a digital image). In the 1st stage compression the raw luminosity record is quickly, yet partially, compressed to available RAM buffer space to allow a user to expeditiously capture a succeeding image. When the higher-priority processes, the user shooting pictures, and stage one compression subside, a 2nd stage compression, which is slower but more effective, decompresses the earlier partially-compressed images, and re-compresses them for saving in flash memory until they are distributed to a remote platform to be finally converted to the JPEG2000 format.

A TCP / IP processor and data processing engines for use in the TCP / IP processor is disclosed. The TCP / IP processor can transport data payloads of Internet Protocol (IP) data packets using an architecture that provides capabilities to transport and process Internet Protocol (IP) packets from Layer 2 through transport protocol layer and may also provide packet inspection through Layer 7. The engines may perform pass-through packet classification, policy processing and / or security processing enabling packet streaming through the architecture at nearly the full line rate. A scheduler schedules packets to packet processors for processing. An internal memory or local session database cache stores a TCP / IP session information database and may also store a storage information session database for a certain number of active sessions. The session information that is not in the internal memory is stored and retrieved to / from an additional memory. An application running on an initiator or target can in certain instantiations register a region of memory, which is made available to its peer(s) for access directly without substantial host intervention through RDMA data transfer.

An array stimulator has a plurality of electrodes in an array (22), the electrodes forming a plurality of electrode pairs, and a signal generator (18) for generating signals to the electrodes so as to generate electrical pulse in a patient to which the stimulator has been applied either transcutaneously or by implantation. Those electrical pulses form a composite pulse in the patient which stimulates the nervous system of the patient. The composite pulse has a duration between 4 μs and 1500 μs and a maximum voltage between 2V and 50V when the stimulator is implanted, and 15V to 500V when applied transcutaneously. The electrical pulses themselves are significantly shorter duration than the composite pulse, so they stimulate the nervous system of the patient much less than the composite pulse or not at all.

A patellar alignment device for determining the position of a patella prosthesis. The device comprises two components-a baseplate and a mobile component which is preferably magnetically attached to the baseplate. During a surgical procedure to replace the knee, the baseplate is temporarily attached to the back of the patella. The baseplate may contain spikes or prongs to secure it to the patella. The baseplate further includes a series of slots for marking the patella. The mobile component resembles a patella and is placed on the baseplate. The patella with the alignment device in place is then placed in position on the knee and trialed. Because the mobile component is free to move on the baseplate, it finds the position that is most amenable to a natural knee movement. The alignment device is then exposed and the patella is marked at the position of the mobile component. Since the baseplate contains a series of slots, the patella can be easily marked at several locations around the mobile component. The entire patella alignment assembly is then removed and the final prosthetic device can be inserted at the marked location.

An integrated circuit includes a plurality of functional blocks. Utilization information for the various functional blocks is generated. Based on that information, the power consumption and thus the performance levels of the functional blocks can be tuned. Thus, when a functional block is heavily loaded by an application, the performance level and thus power consumption of that particular functional block is increased. At the same time, other functional blocks that are not being heavily utilized and thus have lower performance requirements can be kept at a relatively low power consumption level. Thus, power consumption can be reduced overall without unduly impacting performance.

A spectral resistor based on the constitute law of “elasticity of electricity” derived from the Riemann-Lebesgue lemma is provided to build a substantial order-∞ resonant tank. The substantial order-∞ resonant tank according to embodiments of the present invention can function as many different roles such as an electric filter, a harmonic and sub-harmonic power waveform distortion filter, a dynamic damper, a dynamic impedance matching circuit and a kind of electromagnetic wave absorbing material.

Furthermore, the reactive (or so-called regenerated) power caused by the duality of the electric system can be recycled according to embodiments of the present invention.

Systems and methods for improving the reliability of multiprocessors by reducing the aging of processor cores that have lower performance. One embodiment comprises a method implemented in a multiprocessor system having a plurality of processor cores. The method includes determining performance levels for each of the processor cores and determining an allocation of the tasks to the processor cores that substantially minimizes aging of a lowest-performing one of the operating processor cores.

The method may also include identifying processor cores whose performance levels are below a threshold level and shutting down these processor cores. If the number of processor cores that are still active is less than a threshold number, the multiprocessor system may be shut down, or a warning may be provided to a user.

The invention relates to a lithium battery core capable of radiating heat by directly conducting heat from internal to external. The lithium battery core comprises a packaging bag for accommodating a positive electrode, a negative electrode, a separator membrane for separating the positive electrode and the negative electrode, and an electrolyte solution. The packaging bag is also provided with at least one heat radiation fin; and at least one side of the heat radiation fin protrudes out of one side of the packaging bag. Heat produced from the positive electrode and the negative electrode is transmitted to the heat radiation fin through the electrolyte solution, so that efficiency reduction or damage caused by overheating of the lithium battery core can be prevented. Besides, the lithium battery core can be operated in cooperation with a fan or a cooling system, so that heat can be continuously removed from the heat radiation fin, and heat radiation efficiency is increased.

A protocol for an optical network can control the time at which subscriber optical interfaces of an optical network are permitted to transmit data to a transceiver node. The protocol can prevent collisions of upstream transmissions between the subscriber optical interfaces of a particular subscriber group. With the protocol, a transceiver node close to the subscriber can allocate additional or reduced upstream bandwidth based upon the demand of one or more subscribers. That is, a transceiver node close to a subscriber can monitor (or police) and adjust a subscriber's upstream bandwidth on a subscription basis or on an as-needed basis. The protocol can account for aggregates of packets rather than individual packets. By performing calculation on aggregates of packets, the algorithm can execute less frequently which, in turn, permits its implementation in lower performance and lower cost devices, such as software executing in a general purpose microprocessor.
