Method and calculations determine an individual's, or several individuals' simultaneous rates of oxygen consumption, maximum rates of oxygen consumption, heart rates, calorie expenditures, and METS (multiples of metabolic resting rate) in order to determine the amounts of work that is performed by the individual's body. A heart monitor measures the heart rate, and an accelerometer measures the acceleration of the body along one or more axes. An altimeter measures change in altitude, a glucose monitor measures glucose in tissue and blood, and thermometers, thermistors, or thermocouples measure body temperature. Data including body fat and blood pressure measurements are stored locally and transferred to a processor for calculation of the rate of physiological energy expenditure. Certain cardiovascular parameters are mathematically determined. Comparison of each axis response to the individual's moment can be used to identify the type of activity performed and the information may be used to accurately calculate total energy expenditure for each physical activity. Energy expenditure may be calculated by assigning a separate proportionality coefficient to each axis and tabulating the resulting filtered dynamic acceleration over time, or by comparison with previously predetermined expenditures for each activity type. A comparison of total energy expenditure from the current activity is compared with expenditure from a previous activity, or with a baseline expenditure rate to assess the level of current expenditure. A measure of the individual's cardio-vascular health may be obtained by monitoring the heart's responses to various types of activity and to total energy expended.

Lockable portable memory storage devices equipped with male connector plugs have a locking system that prevents access to, and connection of the connector to external devices, and thereby prevents unauthorized use of the device and access to data and/or media stored thereon. The locking system may be incorporated in portable memory devices having a cap or cover that fits over the end of the male plug, a connector plug that pivots relative to its cover or sheath, and devices having a connector plug that is extensible and retractable relative to its cover or sheath; and allows a locking device to be installed on the housing or sheath of the memory storage device, or between the housing and the cover, cap, or sheath that encloses or covers the connector to prevent exposure of the connector to an extent that would allow connection and use of the device.

An electrical outlet, used with a plug having live and neutral prongs of equal length, comprises support member having live and neutral apertures, and live and neutral receptacles for receiving the prongs. A blocking member lies between the support member and the receptacles, and moves between a closed position, in which it blocks the apertures, and an open position, it which it does not block these apertures, thus permitting the prongs to enter the receptacles. The blocking member is biased towards its closed position, but has a cam surface which contacts the entering neutral prong and moves the blocking member to its open position. The blocking member also has a recess so that, when the blocking member is in its closed position, a portion of the live prong can lie within the recess.

A sliding safety structure for power supply receptacles located on a path of a plug prong inserting to a receptacle electrode includes a control dock which has a directing stem, a safety gate slidably located on the directing stem and an elastic element which has two ends pushing respectively the control dock and the safety gate. The safety gate has two force receiving portions which are pushed by the elastic element in regular conditions to block the path of the plug prong inserting to the receptacle electrode and maintain at a latched position. When the plug prong is inserted into the receptacle, the two force receiving portions are depressed by the plug prong to move the safety gate to slide away from the latched position so that insertion of the plug prong to the electrode of the power supply receptacle is allowed. The safety gate also has a stopper below the sliding path thereof to harness the safety gate at the latched position when the two force receiving portions receive uneven forces. Thus an enhanced safety effect can be accomplished to improve the disadvantage occurred to the conventional safety structure which is openable when subject to a force at one side.

Located within a GFCI device having a receptacle is a movable contact bearing arm which is held in either a closed or open position with a fixed contact by a latching member that is connected to the spring loaded reset button. The reset button assumes a first or a second position which is determined by the conductive state of the GFCI. When the GFC is in a conducting state, the reset button is substantially fully depressed within the housing of the GFCI. When the GFCI is in a non-conductive state, the reset button projects outward beyond the top surface of the housing of the GCFI. Thus, the movable contact bearing arm, acting through a latching member, determines the position of the reset button. A blocking member located within the body of the GFCI is positioned by the reset button to allow free access of the prongs of a plug into the openings of the receptacle when the reset button is depressed or to block at least one opening of the receptacle to prevent a plug from entering the openings of the receptacle when the reset button projects out beyond the surface of the housing. Thus, when the GFCI is in a conducting state, the reset button is recessed within the GFCI housing and positions the blocking member to the first position to allow the prongs of a plug to be inserted into the receptacle openings. When the GFCI is in a non-conducting state, the reset button protrudes outward from the housing of the GFCI to position the blocking member to the second position to block at least one opening of the receptacle to prevent the prongs of a plug from entering the receptacle. GFCI's normally have two separate sets of internally located contacts known as bridge contacts where one set is used to connect a load to the source of electricity and the second set is used to connect a user accessible load to the source of electricity. The bridge contacts provide isolation between the conductors to the load and the conductors to the contacts of the GFCI receptacle when the GFCI is in a fault state. In the GFCI here disclosed, the blocking member prevents the prongs of a plug from entering the receptacle when the GFCI is in a fault state and, therefore, can eliminate the need for the bridge contacts.

A tamper resistant assembly provides tamper resistance to an electrical receptacle. A groove has a locking portion connected to a first portion in a base member of the tamper resistant assembly. A first shutter member having first and second resilient arms is slidably connected to the base member. First and second protrusions extend rearwardly from the first and second resilient arms, respectively, and are slidably received in the groove in the base member. The first and second protrusions are disposed in the locking portion of the groove when the shutter member is in a closed position and in the first portion when the shutter member is in an open position. The locking portion prevents separation of the first and second protrusions in the closed position to prevent the first and second resilient arms from being separated and to prevent insertion of an object therebetween.
