摘要:
The present invention relates to a Mobile Ad Hoc Network that possesses sufficient intelligence to handle a collection of devices that differ in terms of features either inherent to the device or the environment in which they operate. The different features inherent to the device may consist of different hardware and software technologies (e.g., combination of RF for transmission ability, processing ability, power supply, and interfaces). The different features of the environment may consist of any telemetry data measuring the state of the environment, as well as information regarding the MANet such as the density of devices in the vicinity of a device. Various applications are considered.

摘要:
A reel comprises a cylindrical core composed of two complementary arcuate core segments, a pair of flanges disposed respectively at axially spaced opposite ends of the core, and a pair of rings for connecting the core to the flanges. The rings are fixed respectively to facing inner sides of the flanges. Cooperating slots and tongues on the rings and core elements prevent the flanges from moving relative to the core in the direction of the axis of the core. The tongues enter the slots when the core segments are brought together. Resiliently bendable locking arms protrude radially inward from both ends of each core segment, and each locking arm is engageable by a snap fit with one of the rings when the core segments are brought together. Access openings in the flanges adjacent each of the locking arms allow access to the locking arms for disengagement from the rings.

A grass treatment device height adjustment assembly for adjusting the height of a grass treatment tool above ground level includes a height adjustment mechanism and an elongate rotational element, such as a roller, having first and second ends. The rotational element has an axle extending substantially along the longitudinal axis of the element about which the element rotates. The height adjustment mechanism includes a rotatable member connected to the axle of the rotational element wherein the rotatable member is associated with a second fixed axis of rotation that is substantially parallel to but offset relative to the first rotational axis. The second axis of rotation enables the height adjustment mechanism to adjust the position of the first axis of rotation relative to the second axis of rotation.

A spa cover lifter for moving a spa cover from a closed position to a storage position includes a drive mechanism, a fixed base and a lifting arm assembly. The lifting arm assembly is mounted to first or second leaves of the spa cover. The lifting arm assembly is driven by the drive mechanism and is moveably mounted to the fixed base. The lifting arm assembly includes a cover pivoting assembly and a cover transporting assembly. The cover pivoting assembly is driven by the drive mechanism to move the cover from the closed position to an intermediate position and the cover transporting assembly is driven by the drive mechanism to the move the cover from the intermediate position to the storage position. The spa cover lifter has an automatic shutoff for cutting power when an obstacle is encountered. A method of moving the spa cover is also disclosed.

There is disclosed a method of generating synthetic speech sound data relating to first and second utterances. Interpolation between or extrapolation from first and second sets of parameters encoding said utterances results in a third set of parameters used to synthesise the synthetic speech sound. Each set of parameters preferably includes separate source parameters and spectral parameters derived using linear prediction coding. Related methods of trailing and diagnosis, and related apparatus are also disclosed.
摘要:
The synthesizer and method provide a relatively wideband swept frequency signal and include generating a first swept frequency signal with a first generator, and successively switching between different frequency signals with a second generator. Such switching creates undesired phase discontinuities in the output swept frequency signal. The first swept frequency signal is combined with the successively switched different frequency signals to produce the relatively wideband swept frequency signal, and the second generator is calibrated to reduce the undesired phase discontinuities during switching based upon the output swept frequency signal.
