A cellular wireless packet data communication system containing transmit-only endpoint devices which transmit to receive-only base stations. The system is configured to allow for large area coverage (e.g., a metropolitan area) with far fewer number base stations than are required with conventional two-way cellular systems. The base station coverage areas are configured to overlap, allowing for reception of packets at multiple base stations. A data concentrator resolves redundantly received messages. The network is configurable as a WAN, a LAN, or a combination of the two. Novel modulation techniques (e.g., a 16QAM submodulation together with a 7FSK modulation) are used such that low cost components can be used in the transmitters and receivers while achieving outstanding probability of success performance. The endpoint devices are battery operated and accordingly, are designed for low power consumption and multi-year battery life. The system is used in a variety of applications including remote monitoring and mobile communications.

A position detection apparatus, with which the setting position adjustment of imaging sections is not required and the maintenance can be made easily, structuring of which can be realized with low-cost components, is provided. In the position detection apparatus, imaging sections (7), each of those which includes an area image sensor (70), in which light-sensitive elements are arrayed in a two-dimensional pattern, and an image formation lens (71), are placed to the lateral two points of a detection plane (1), respectively. A selection device (10) selects particular pixels corresponding to a particular field of view of a reflex reflection frame (4) or the like from the light-sensitive elements within a range of a given field of view having been imaged by the imaging sections (7). An image processing device (11) image-processes a particular image signal corresponding to the selected particular pixels and then outputs an indicating position coordinate of a pointing device (2).

A method for controlling an autonomous vehicle includes obtaining information describing a roadway; defining a plurality of layers along the roadway between a starting position and a goal position, each layer having a first width, and each layer having a plurality of nodes that are spaced from one another transversely with respect to the roadway within the first width; and determining a first trajectory from the starting position to the goal position, by minimizing a cost value associated with traversing the layers. Determining the first trajectory includes, for each layer, determining layer-specific weighting factors for each of a plurality of cost components, based on information associated with the respective layer, and determining, for each node of the respective layer, a cost for travelling to one or more of the nodes in a subsequent layer based on the plurality of cost components and the layer-specific weighting factors.

A tool and methodology are described that can evaluate the trustworthiness of a system. In one embodiment, the system is classified in terms of the resources that constitute the system, the codes that apply to the system, the services produced by the system, the risks incurred by the system, and the costs associated with its use. A functional component of a trust decision to use the system involves a calculus to evaluate whether the probability that the services as a result of using the system will exceed the risks that may occur as valued by a user. The cost component of a trust decision includes an evaluation that the use of a system will occur at an acceptable cost and will produce economically acceptable results.

A computing system and methods for memory management are presented. A memory or an I/O controller receives a write request where the data two be written is associated with an address. Hint information may be associated with the address and may relate to memory characteristics such as an historical, O/S direction, data priority, job priority, job importance, job category, memory type, I/O sender ID, latency, power, write cost, or read cost components. The memory controller may interrogate the hint information to determine where (e.g., what memory type or class) to store the associated data. Data is therefore efficiently stored within the system. The hint information may also be used to track post-write information and may be interrogated to determine if a data migration should occur and to which new memory type or class the data should be moved.

Motorcycle, marine, and racing components are formed of a conductive loaded resin-based material. The conductive loaded resin-based material comprises micron conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers in a base resin host. The percentage by weight of the conductive powder(s), conductive fiber(s), or a combination thereof is between about 20% and 50% of the weight of the conductive loaded resin-based material. The micron conductive powders are metals or conductive non-metals or metal plated non-metals. The micron conductive fibers may be metal fiber or metal plated fiber. Further, the metal plated fiber may be formed by plating metal onto a metal fiber or by plating metal onto a non-metal fiber. Any platable fiber may be used as the core for a non-metal fiber. Superconductor metals may also be used as micron conductive fibers and/or as metal plating onto fibers in the present invention.

A multi-path digital power supply controller includes a first ADC (ADC1) coupled to the supply's output voltage V_out and arranged to provide an output which varies with V_out's low frequency components, and a second ADC (ADC2) coupled to V_out and arranged to provide an output which varies with V_out's high frequency components. A digital reference value is subtracted from the output of ADC1 to produce a low frequency digital error signal, and a summing circuit sums the low frequency digital error signal and the output of ADC2. Processing circuitry is arranged to produce an output which varies with the summed signal and is suitable for coupling to a power stage for use in regulating V_out. Preferably, ADC1 is a low-bandwidth high-resolution ADC and ADC2 is a high-bandwidth low-resolution ADC, both of which are low-cost components.

Methods and apparatus are provided for frequency and power scaling a drive assembly for a brushless direct current (BLDC) motor. The apparatus comprises multiple groups of half-bridge switching element assemblies connected to respective “In-Hand” phase windings of the BLDC. Each group of half-bridge assemblies receives time sliced commands from a processor so that the resultant frequency of the output drive signal can be higher than the frequency capability of an individual switching element. By effectively paralleling groups of half-bridge assemblies connected to respective In-Hand phase windings, the current delivered to the phase windings can be greater than the individual current capability of the switching elements in the half-bridge assemblies. The electromagnetic field generated in the “In-Hand” phase windings forces essentially equal current sharing in the respective driver switching elements. The disclosed techniques enable frequency and power scaling of motor drive assemblies using standard low-cost components.
