Abstract: A carrier evaluation system and method configured as a detection tool for use with a cross belt sorter having a plurality of carriers disposed for movement along a travel path and comprises at least one sensor configured for mounting to the cross belt sorter so as to be disposed beneath carriers of the cross belt sorter along the travel path of the carriers and operable for measuring an upward distance from the sensor to a lower portion of the carriers as the carriers pass over the sensor while moving along the travel path. The sensor may be used to measure carrier height and/or distances to an array of magnets for detecting missing magnets. A pair of spaced apart sensors may be used for measuring carrier pitch. The system further provides an alert if the upward measured distance is outside a predetermined limit.

Abstract: An electronic hand held communications and data storage device (10) capable of sending and receiving small packets of data; the device including a display (13) capable of displaying said data, user control means (14) to enable sending and receipt of said information; wherein, the control means (14) is disposed within a field defined by the display (13). The control means (14) is arranged to allow a user a capability to pre determine commands for device function initiation.

Abstract: A mixture of two or more calcium phosphate compositions are combined with an aqueous solution and are useful as bone fillers on bone cements such as orthopedic and dental cements and remineralizers. The mixtures self-harden to substantially form hydroxyapatite, the mineral phase of bone and tooth enamel. The at least one or more of precursors is prepared in a manner resulting in its having an extremely low moisture level. The use of low moisture components results in an improved shelf life to the mixture.
