Abstract: A rotary electric shaver generally includes a handle assembly having a longitudinal axis, and a head assembly attached to the handle assembly. The head assembly includes a plurality of outer cutters and a plurality of inner cutters, and a tray on which hair cut by a first one of the pairs of cooperating cutters is permitted to commingle with hair cut by a second one of the pairs of cooperating cutters. The head assembly is pivotably mounted on the head assembly mount such that the head assembly is capable of pivoting movement relative to the handle assembly about the entire circumference of the head assembly.

Abstract: A rotary electric shaver generally includes a handle assembly having a longitudinal axis, and a head assembly attached to the handle assembly. The head assembly includes a plurality of outer cutters and a plurality of inner cutters. Each of the inner cutters is paired with one of the outer cutters for cooperating to cut hair. The head assembly also includes a tray on which hair cut by a first one of the pairs of cooperating cutters is permitted to commingle with hair cut by a second one of the pairs of cooperating cutters. The head assembly further includes a fastener that extends longitudinally for attachment of the head assembly to the handle assembly such that the tray pivots relative to the handle assembly. The head assembly further includes a biasing element that circumscribes the fastener to bias the tray from a pivoted position into a non-pivoted position.

Abstract: A rotary electric shaver generally includes a handle assembly including a housing, a motor disposed in the housing, a plurality of drive shafts operatively connected to the motor and extending at least in part exterior of the housing, and a head assembly mount separate from the plurality of drive shafts, wherein the head assembly mount has a longitudinal axis. A shaver head assembly is positionable on the handle assembly, and the shaver head assembly has a circumference and includes a plurality of inner cutters each operatively connectable to a respective one of the drive shafts for conjoint rotation therewith, and a plurality of outer cutters each corresponding to a respective one of the inner cutters. The shaver head assembly is configured for mounting on the head assembly mount such that the shaver head assembly is capable of pivoting movement relative to the handle housing about the entire circumference of the shaver head assembly.

Abstract: A methodology is provided for processing carriers in a wireless application whereby the outputs of a multiplicity of modulated RF signal sources are combined into a single RF signal stream, that single RF signal stream being thereafter divided among the inputs of another multiplicity of RF power amplifiers. The outputs of that multiplicity of RF power amplifiers are then recombined, filtered and provided as an input to a transmission antenna.

Abstract: Therefore a method and apparatus for controlling a linear amplifier processing a plurality of carrier signals of a multi channel carrier system alters the phases of one or more sources of the multi-channel signals in response to a detected peak envelope power or of a peak to average power ratio at regular scheduled intervals. This reduces the peak envelope power to average envelope power ratio and enables the reduction in the power rating required by the amplifiers handling the multi-channel signal.

Abstract: A method of and apparatus for monitoring the output signals of a power converter, having galvanic isolation between the input and output, observes the voltage and current on the primary side of the converter as reflected through a tertiary winding or influenced through the primary winding of the power transformer and applies error corrections thereto to replicate the output signal. These corrections are arrived at by compensating for operational differences between input and output circuitry and by emulating, on the primary side, the output side circuitry that causes the differences between the output signal and the reflected signal, and the conditions to which the output side circuitry is subjected. The resulting replicated signal is applied to feedback control circuitry, in lieu of the actual output signal, and used to regulate the output of the power converter.

Abstract: A power inverter efficiency is optimized at high frequency in a fully resonant inverter operating with a range of load impedance that takes into consideration switching loss and conducting loss as a combined overall effect. Within this range of load impedance the inverter is constrained to operate with switching loss which is generally considered unacceptable in a conventional high frequency high efficiency power inverter, but the overall combined high efficiency of the disclosed power inverter has a wider range of load impedances than has been previously achieved in such a resonant power inverter. Non-linear capacitance across switching the device is positively utilized in achieving this goal.
