Abstract: A toenail trimmer is configured to aid elderly and flexibility-challenged individuals, and includes: a housing with an opening; a cutting member mounted within the housing with a portion proximate to the opening; a motor to drive the cutting member to remove a portion of a toenail inserted through the housing opening; and a shaft, with the housing positioned proximate to a first end of the shaft. The shaft includes a support member, such as a cuff, that is configured to releasably secure a first portion of the shaft to the user's upper arm, and an ergonomic handle portion configured for grasping by the user's hand. The ergonomic handle portion and the support member provide stable support for the toe nail trimmer at two positions with respect to the user's arm during use of the toe nail trimmer. The handle may cooperate with a base to provide support/guidance thereto.

Abstract: A nail groomer to aid elderly and flexibility-challenged individuals, is convertible between: a first configuration adapted for filing toenails, and a second configuration adapted for filing fingernails. The nail groomer includes: a grooming head, shaft, and handle configured to be grasped by a user's hand to manipulate the nail groomer. The grooming head has a housing, a motor, and a filing bit with an abrasive surface. The motor rotates the filing bit, so the abrasive surface can abrade portions of a nail. A housing opening releasably receives one end of the shaft, to form the first configuration, and a particular shaft length permits positioning the filing bit at a user's toenails when the handle is grasped and manipulated by the user. With the shaft detached from the grooming head, the user grasps and manipulates the grooming head's housing directly with one hand, for filing of fingernails of the other hand.

Abstract: A method of validating connections in an optical add/drop multiplexer (OADM) that includes a plurality of modules configured to route optical signals through the OADM, and at least one multi-fiber cable connecting modules of the OADM. A light source coupled to a first port of a first module is controlled to emit a test light. A determination is made whether or not the test light is received at a first photo-detector connected to a second port. Continuity of a connection between the first port and the second port is validated when the test light is received at the first photo-detector.

Abstract: Methods and systems for enhancement of device accessibility are described. In an example, an operating system configured to be executed on a device, may be configured to support a plurality of software applications and to support a plurality of modes of operation of the device. A given software application may include a user-interface comprising a user-interface item having a text in a first language. The operating system may be configured to receive a selection of the user-interface item of the given software application. Based on the operating system being in an accessibility mode common to the plurality of software applications, the operating system may be configured to determine a translation of the text into a second language; and a voice output corresponding to a spoken utterance of the translation of the text. The operating system further may be configured to provide, by the device, the voice output.

Abstract: The present invention relates to a method, apparatus, system and computer program product, wherein a time division multiplex signal is received with a periodic first time period allocated to a downlink transmissions and a periodic second time period allocated to uplink transmissions. A decision time metric is obtained by correlating the received signal with a replica signal in order to detect a synchronization pattern provided in the first time period. Then, a slide window based normalization with a time window long enough to accommodate said second time period is applied to the decision time metric.

Abstract: A method is provided for facilitating efficient usage of radio capacity in a radio communication system including a communication station operable to receive, over a plurality of subchannels of the radio communication system. In this regard, the packet-formatted data has an overall sequence, and is divided into a plurality of portions receivable by the communication station over respective subchannels, where each portion has a respective link sequence. The method includes detecting missing packet-formatted data at the communication station based upon the overall sequence or at least one of the link sequences. Then, when the missing packet-formatted data is detected based upon the overall sequence, a time period is timed, and when the communication station fails to receive the missing packet-formatted data before the step of timing times out, retransmission of the missing packet-formatted data is requested.

Abstract: A method determines whether information corresponding to one of a number of carriers indicates the one carrier is loaded or unloaded, wherein the carriers are used for transmission of a MAC flow by the access terminal over a reverse link. Responsively, the transmission resource allocation corresponding to the MAC flow for the one carrier is adjusted based on information corresponding to carrier loading for each of the carriers and on information corresponding to reverse link pilot power for each of the carriers. An access terminal includes a function that determines whether the one is loaded or unloaded. Responsively, the function adjusts transmission resource allocation for the MAC flow for the one carrier based on information of carrier loading for each of the carriers and on information of reverse link pilot power for each of the carriers.

Abstract: A dimming ballast lamp includes a lamp, a ballast circuit for converting AC input power to AC output power, a dimming interface circuit for generating a dimming control signal having a voltage level indicative of a selected dimming level of the lamp and a dimming circuit responsive to the dimming control signal for controlling operation of the ballast circuit. A feedback control circuit detects the lamp voltage and produces a feedback control signal in response to the lamp voltage exceeding a perscribed threshold voltage level. The dimming circuit, responsive to the feedback control signal, controls operation of the ballast circuit so as to increase lamp current thereby increasing the dimming level of the lamp, ensuring low temperature ignition of the lamp and protecting against lamp shutdown.

Abstract: A lamp controller includes an interface circuit, or receiver, which receives an input signal and decodes control signals supplied from a transmitting device, such as a power line wall controller, according to at least two of the following communication techniques: phase angle control, step control, and coded control. The receiver tests the input signal and identifies which type of control technique is employed by the wall controller connected to the lamp controller. The receiver then decodes the control command from the input signal. In a disclosed embodiment, the lamp controller is gas discharge lamp dimming ballast having a two wire input for connection to the hot dimmed and neutral leads of the power line controller. The ballast has an improved topology in which a pre-conditioner supplies a substantially constant DC voltage to a ballast stage including an inverter, a resonant tank output and a control circuit.
