Abstract: An asset location system comprising a plurality of location tags, each having: a location tag transmitter for controlled range transmission of a location identifier; a plurality of asset tags, each being affixed to an asset and each having: a receiver for receiving a location identifier from any of the location tags; a memory for storing at least an asset identifier and a location identifier; a transmitter for transmitting an asset signal, the asset signal including at least the asset identifier and the received location identifier; and an asset location retrieval unit, the retrieval unit having: a receiver for receiving the asset signal from any of the asset tags; a memory; a power unit; and an output means for outputting asset locations based on the received asset signal from any of the plurality of asset tags.

Abstract: A lifting jack includes a lifting mechanism pivoted to a base and a support bracket member so as to lift or lower the support bracket member relative to the base, a driving shaft journalled on a right link pin to be rotated so as to move a left link pin relative to the right link pin, a reflecting member hinged to the base so as to enable the reflecting member to be displaced from a folded position to an unfolded position and to be disposed to reflect images of an object lifted by the support bracket member. Preferably, a lighting device is disposed to illuminate a desired area of the object. Two limit switches are disposed to prevent excess movement of the bracket support member.

Abstract: An isometric exercise device including a stretchable member and a vibratory portion. The isometric exercise device enables a person to perform an isometric exercise using the stretchable member while the vibratory portion generates vibratory pulses that are useful in providing a massaging action to a portion of the person's body.
