Improved timing synchronization and access control techniques for use in an orthogonal frequency division multiplexed (OFDM) wireless system or other type of wireless communication system. In accordance with the invention, an uplink synchronization and access control system is provided in which mobile stations transmit certain timing and access signals in dedicated intervals in an uplink stream. Access control is illustratively implemented as a two-stage process in which a given mobile first transmits a generic uplink access signal in one of the intervals. If this access is accepted, the base station transmits an access acknowledgment containing initial timing and power corrections, along with initial channel assignments on which the mobile can initiate a call set-up process. For re-synchronization, mobiles transmit timing synchronization signals in the dedicated timing and access intervals. The base station measures the arrival time of the signals, and sends back appropriate timing corrections. The invention thereby ensures that orthogonality between mobiles is maintained.

The invention concerns a method for coordination of the interference in the uplink between cells (B1, B2) of a single frequency network with the frequency band used for uplink being subdivided into at least two subsets (F1 F2 . . . FR), whereby a resource related to a dedicated subset is allocated to a mobile terminal (T1) located in a first cell (B1) of said cells in the border area to a neighbor cell (B2-B4), the base station of the cell (B2) with the highest interference damage caused by the mobile terminal (T1) accepts a high interference level on said dedicated subset dependent on network criteria, and the usage of said dedicated subset in the cell (B2) with the highest interference damage caused by the mobile terminal (T1) is restricted under observation of the interference level, a base station, a mobile terminal and a mobile network therefor.

A biosensor for monitoring an analyte content with a partial voltage generated therefrom is provided. The present biosensor includes a chip having a resistance R_s, a power source, and a microprocessor. The power source is used for supplying an applied voltage on the chip. The chip generates a time-dependent response current in response to a content of an analyte of a specimen applied thereon upon supplying the applied voltage on the chip. The microprocessor receives a time-dependent partial voltage caused from the chip due to the time-dependent response current, and determines the content of the analyte in accordance with the time-dependent partial voltage. The present biosensor is provided with fewer elements than a conventional one. A purpose of cost down is thus obtained.

The light redirecting films of the present invention have a pattern of individual optical elements that may intersect and/or interlock each other to achieve substantially complete surface coverage of at least one of the surfaces occupied by the optical elements. At least some of the optical elements may have at least one flat surface and at least one curved surface that may intersect each other to a greater extent on the curved surface than on the flat surface to increase the relative percentage of flat surface area to curved surface area of the intersecting optical elements to increase the on axis gain of light passing through the film.

A remotely accessible power controller communicates power reduction command signals by power line carrier (PLC) signaling over existing AC power distribution conductors for automatically disconnecting building lighting loads. Turn-off command signals from a local or remote controller automatically disconnect building lighting loads according to a time-of-day schedule to comply with mandated energy consumption codes applicable to the automatic shutoff of electrical lighting. Load shedding (selective turn off and/or dimming) command signals transmitted from public or private utility companies automatically disconnect or reduce building lighting loads in accordance with load curtailment agreements to limit total connected power consumption below an agreed level. The power controller is connected by a minimum amount of retrofit wiring into an existing end-user alternating current power distribution network, for example, a building power distribution network having AC power conductors that service multiple lighting loads interconnected in one or more power phase groups. Each dimming lighting load is equipped with an addressable dimming module for decoding and executing dimming and turn-on and turn-off power reduction commands. Fluorescent lamps are equipped with addressable electronic dimming ballasts.

The abstract display mode is combinable with the topology display mode. Finally, the automatic positioning of components according to predefined topology templates is provided.

The invention discloses a method based on monocular vision for detecting and roughly positioning the edge of a road, and relates to the field of machine vision and intelligent control. Aiming at a continuous road with different edge characteristics, two road edge detection methods are supplied and suitable for semistructured and nonstructured roads and can be applied to vision navigation and intelligent control over a robot. The invention provides a method for detecting the edge of the road based on colors and a method for detecting the edge of the road based on threshold value partitioning. On the basis of the obtained edge of the road, an image is subjected to inverted perspective projection transformation, so that a front view is transformed into a top view; and according to a linear corresponding relation between a pixel and an actual distance in the image, a perpendicular distance from the current position of the robot to the edge of the road and a course angle of the robot can be calculated. The method is easy to implement, high in anti-interference performance, high in instantaneity and suitable for the semistructured and nonstructured roads.

An adaptive architecture for electric motors, generators and other electric machines. An adaptive electric machine provides optimal performance by dynamically adapting its controls to changes in user inputs, machine operating conditions and machine operating parameters. Isolating the machine's electromagnetic circuits allows effective control of more independent machine parameters, enabling greater freedom to optimize and providing adaptive motors and generators that are cheaper, smaller, lighter, more powerful, and more efficient than conventional designs. An electric vehicle with in-wheel adaptive motors enables delivery of higher power with lower unsprung mass, giving better torque-density. The motor control system can adapt to the vehicle's operating conditions, including starting, accelerating, turning, braking, and cruising at high speeds, thereby consistently providing higher efficiency. A wind powered adaptive generator can adapt to changing wind conditions, consistently providing optimal performance. An adaptive architecture may improve performance in a wide variety of electric machine applications, particularly those requiring optimal efficiency over a range of operating conditions.
