Abstract: A contact tracking method and a related server are provided. In the method, the positioning information of multiple user equipments (UEs) is obtained. The UEs transmit wireless signals. The positioning information is determined based on the wireless signal. The wireless signal indicates a network provider identifier, a signal strength, or geolocation. The travel routes of the UEs are determined. Each travel route records the positioning information of one UE over time. The travel routes are analyzed to determine a contact situation between a first UE and a second UE of the UEs based on a contact criteria.

Abstract: A shoulder prosthesis includes a humeral portion and a scapular portion, each having an osseointegrable component and an articular component. The osseointegrable component in the humeral portion includes a humeral body produced as a semicircular asymmetrical cage having a proximal circular ring base facing the scapular portion and an eccentric distal cylindrical base in opposite position, which are connected by arms having one or more holes for favoring the growth of bone tissue and facilitating anchorage to the bone, the proximal circular ring base being configured to be interchangeably coupled with the articular component for an anatomical prosthesis or a concave insert for a reverse prosthesis. The osseointegrable component in the scapular portion includes a glenoid base-plate of asymmetric form for coupling to an articular component, such as a concave glenoid insert, for an anatomical prosthesis or a glenosphere for a reverse prosthesis.

Abstract: The holographic manufacture of Compact Discs has three stages namely mastering, production of the sub-master holograms and replication. In the production stage, a holographic plate, spacer and master transparency are positioned against a prism, and then illuminated with split beams from a laser in order to record a hologram, at the plate, of the master transparency. The resultant hologram of the plate is then mass replicated on polycarbonate or photochromic discs to produce compact Discs compatible to conventional Compact Disc players.

Abstract: An improved retractible fly tying bobbin having means for maintaining tension on the thread while tying the fly and also means for quickly relieving all the tension on the thread when the tying is completed. The bobbin is compact and utilizes two cupped shaped cylindrical halves which engage each other in a drive fit, wherein one cylindrical half is driven and the other half is the driver, tension on the thread can be adjusted prior to assembly of the bobbin to keep the thread taught while winding without causing the thread to break.

Abstract: The invention relates to a multiple relay comprising a control relay (9) a plurality of individual relays (8). The "fixed" contacts of the individual relays (8) are in fact, only semi-stationary and are carried on a common insulator bar (4) which pivots on an axis (5) under the control of the control relay. Each semi-stationary "fixed" contact of an individual relay is connected to a conductor bar (6) (one conductor bar per semi-stationary contact of the relay) carried by the common bar. Electrical contact between a semi-stationary contact and a moving contact is established by energizing the control relay then the individual relay and by de-energizing the control relay and then the individual relay; the semi-stationary contact locks the moving contact. Electrical contact is broken by momentarily energizing the control relay.
