Accessory device authentication techniques are described. In one or more embodiments, connection of an accessory device to a host computing device is detected. Responsive to the detection, an authentication sequence may occur to verify an identity and/or capabilities of the accessory device. Upon successful authentication of the accessory device, the host device may authorize the accessory device for power exchange interactions with the host device. The host device may then draw supplemental power from a power source associated with the authorized accessory device, such as a battery or power adapter. The host device may also enable the accessory device to obtain and use power supplied by the host device in some scenarios. Power exchange between a host device and an authorized accessory may be managed in accordance with capabilities of the accessory device that are identified during authentication.

A memory array comprising a number of memory cells, a set path, a signal path, and at least one word line for transmitting a word line select signal to a row of the memory cells. The word line extends from a first driver end to a second end. The memory array further includes a dummy word line extending from the first driver end to a point between the first and second ends and back to the first end for transmitting a tracking signal responsive to the word line select signal. By folding the dummy word line in this manner, improved tracking of the set path with the signal path is achieved.

A method of forming a seal ring includes heating an extruded rod to a temperature above a glass transition temperature. The extruded rod has first and second ends. The method further includes bending the extruded rod into a circular structure while the temperature is above the glass transition temperature, joining the first and second ends of the extruded rod to form a semi-finished ring, and annealing the semi-finished ring.

An associated memory structure having a plurality of memories amenable for testing and a method of testing the memories is provided. First and second memories are formed, wherein data in the first memory provides a basis for at least a portion of the input to the second memory during functional operation of two memories. Preferably, an output latch for receiving the output test data from the first memory is provided. Means are provided for loading the first memory with data which is utilized as a basis for providing at least a portion of the input to the second memory. An access path from the output port of the first memory to the input port of the second memory allows use of the data in the first memory to generate at least a portion of the input to the second memory. The first memory is first tested independently of the second memory. Thereafter, the first memory is loaded with preconditioned data that is used as a basis for inputs to the second memory during testing of the second memory. The second memory is then tested by generating inputs to the first memory during testing of the second memory. Thus, outputs of the first memory constitute at least a portion of test data inputted to the second memory. A latch is provided to capture the output of the test data from the second memory.

A composite material includes a thermoplastic material, and a metallic filler dispersed within the thermoplastic material. The metallic filler may be fibrous, particulate or a combination thereof. The metallic filler may have a length in a range of about 3 mm to about 10 mm, and/or a mean particle size of about 2 microns to about 10 microns. The composite material may have a volumetric resistivity of not greater than about 0.5 Ohm·cm. The composite material can be in the form of a sealing component.

This invention relates to a new and distinct cultivar of Hydrangea macrophylla (Thunb.) named `Ravel` which originated as a sport from the inventor's controlled commercial growing of the non-patented Hydrangea macrophylla cultivar `Merritts Supreme`, and is distinguished from its parent by the unique pigmentation pattern which causes the florets and inflorescence to be both pink and white, and gives each floret a white center and four pink fan-shaped points at the outer edges, resulting in a pink and white flower at the peak of its bloom, not predominantly a pink flower. The new variety `Ravel` further possesses the favorable characteristics of: agressive, compact growth habit; long lasting large flowers and the ability to be easily forced in a greenhouse for flowering in the spring.

A truc/complement receiver driver circuit in which the input signals may be applied prior to a sysnchronous clock signal. The input signals are sensed and latched to generate complementary output signals. The generation of the output signals causes the receiver portion of the circuit to be automatically reset for the next cycle. The leading edge of the systemclock causes the circuit outputs to reset and enables the receiver circuit to be enabled for the next cycle. Multiplexed input receiver circuits allow the circuit to respond to a plurality of input signal sources.
