摘要:
The exercise performance monitoring glove consists of a pair of flexible gloves that have embedded pressure sensor arrays to measure hand pressure applied to them during physical activities such as exercise. Each glove sends its pressure data in a real-time format using an embedded wireless RF transmitter to the opposite glove. The gloves then compare the pressures and provide feedback through a user selectable choice of either audio, visual or vibratory methods. Audio feedback is provided to earbuds using typical connection means such as Bluetooth connection to a smartphone or remote device having an exercise performance monitoring app. Visual feedback is provided in several possible modes such as text, color, and graphics using an embedded wraparound flexible display screen. Vibratory feedback is provided using embedded vibration devices inside the gloves. Once a specific feedback mode is selected using the performance monitoring app, the user will know whether the gloves are in a balanced or unbalanced state. Using this real-time feedback allows the user to make corrections in the hand grip forces to achieve a balanced state. The gloves can be used in a wide variety of situations such as exercise, sports, and for medical rehabilitation where body balance is important.

A surgical jig for determining an axis extending into the end of a bone (2). The jig comprises a platform (10) arranged to be supported upon a resected surface (4) at an end of a bone (2), first and second clamps (16) and an alignment guide (18). The first and second clamps (16) are coupled to the platform (10) and are arranged to engage first and second portions of a bone lip (6) extending around at least part of the resected surface (4) to secure the platform (10) to the resected surface (4). The alignment guide (18) defines an axis extending into the end of the bone (2), the alignment guide (18) being pivotally coupled to the platform (10). A method of determining an axis extending into the end of a bone (2) using the surgical jig is also disclosed. The method comprises resecting the end of a bone (2) to leave a bone lip (6), coupling the surgical jig to the resected end of the bone (2), and pivoting the alignment guide (18) until the alignment guide (18) coincides with a required axis extending into the end of the bone (2).

A portable electronic device and a method to protect the portable electronic device from a battery bounce are provided. The portable electronic device (100) can comprise a free-fall condition sensor (105) enabled to detect a pre-battery bounce condition in the portable electronic device and a processor (110) coupled to the free-fall condition sensor (105). The processor (110), in response to a detection of the pre-battery bounce condition by the free-fall condition sensor (105), can be programmed to place the portable electronic device (100) in a pre-battery bounce setting. The method can include detecting a pre-battery bounce condition in the portable electronic device (405) and in response to the detection of the pre-battery bounce condition (405), placing the portable electronic device in a pre-battery bounce setting (410).

A charging system (108) supplies a source voltage (Vco, FIG. 5) and a source current (Ico, FIG. 5) to a plurality of battery cells (110). The charging system operates according to a method (200) including the steps of determining (202) a capacity for each of the plurality of battery cells, determining (204) a desired cutoff current (Ico1, FIG. 5) for a select one of the plurality of battery cells (110A) having the smallest capacity, determining (206) an optimal source current according to the capacity of the select one of the plurality of battery cells, and adjusting (208) the source current according to the optimal source current.
摘要:
A high frequency, high speed data communication system for providing electronic mail, file transferring, Internet access, weather forecasts and other database and communication options to remote HF/MF users, such as vessels at sea. A conventional, multi-featured, land-line bulletin board system is employed at a central communication facility for the provision of data communication services. A remote computer accesses an HF/MF link at the central communication facility via an HF/MF modem coupled to an HF/MF radio and antenna. The HF/MF link includes an antenna, HF/MF radio, HF/MF modem, and an interface computer for performing protocol and interface conversion between the land-line BBS and the HF/MF modem. Multi-user capability is provided through the simultaneous employment of multiple HF/MF links at the central communication facility. Multi-frequency operation of each HF/MF link is provided through the scanning of each HF/MF radio in conjunction with an antenna tuning system. The antenna tuning system provides virtually instantaneous tuning of an antenna among a predetermined set of frequencies through the switching in of one of a set of pre-tuned manual antenna tuners. A centralized scanning computer facilitates multi-frequency operation through the dynamic reallocation of assigned frequencies among the various HF/MF links so that any links which are not busy servicing users can be employed to scan available frequencies.

The exercise performance monitoring apparatus consists of gloves and shoes that have embedded pressure sensor arrays to measure pressure applied to them during exercise. The gloves and shoes send the pressure data using wireless RF transmitters to a central display control unit located on each glove. The gloves have color LED strips which change color depending on whether the gloves or shoes are measuring equal pressures. The glove displays the state of balance between the glove and shoe pressures using separate LED displays on each glove. The pressure balance is adjustable as well as the selection of colors to display. The user can at a glance see if he or she is in balance when performing the specific exercise by observing the color shown on the glove display. The glove display for either glove or shoe pressure will flash the color representing unbalanced pressures if the pressures are unbalanced on the glove having the highest or lowest pressure depending on user preference. A steady color is shown when the pressure is balanced and then changes color as soon as the pressures become unbalanced. A wireless enabled device such as a smart phone can also be used to monitor the exercise in lieu of using the glove LED display.

A method of determining the offset of the head part of an orthopaedic joint prosthesis stem component, relative to the neck of the stem part on which the head part can be fitted, involves obtaining a first and second images of the patient's joint on a non-coincident first and second planes. Template parts are fitted to the first and second images of the bone, which have markings on them which can be placed relative to the head part and the stem part respectively of the patient's bone, and scales for measuring first and second displacements which are the distances between the axis of the head part and the axis of the neck of the patient's bone measured in the first and second planes.

A bottle cap remover includes a pair of axially nested socket sections of different diameters depending axially from a larger-diameter grasping section. Each of the socket sections includes frictional gripping members along their inner walls that are adapted to frictionally engage different sizes and types of metal and plastic bottle caps, thereby to enable the user to twist off and remove the bottle caps by applying a relatively small twisting force to the grasping section.
