Patent CA-2104241-C (CA)
Inventor: BEARDSLEY GILBERT DEAN
IPC: B25B23/00

Abstract: A socket tool extension element includes a latching mechan-ism for automatically securing a socket to a driven stud on one end of the extension simultaneously with the attachment of a wrench drive stud to a socket portion at the opposite end of the extension. A captive latch ball projecting from an opening on one side face of the driven stud is constantly biased to the projected position by one end of a compression spring housed within a latching bore angularly disposed relative the longitu-dinal axis of the extension element. The other end of the com-pression spring constantly engages a bearing member which in turn biases against a lock pin slidably disposed within a bore axially extending from the socket portion to the driven stud of the extension element. In an at-rest condition and with a socket attached to the driven stud, the socket is manually attachable and removable from the driven stud and temporarily retained thereupon by the yieldably biased latch ball. Thereafter, upon the attachment of a wrench drive stud to the extension socket portion, the drive stud engages an end of the lock pin, causing its axial displacement to force the bearing member toward the captive latch ball and full compressing the helicies of the compression spring so as to preclude any inward deflection of the latch ball such that the attached socket is non-removably re-tained or locked upon the extension element as long as the wrench drive stud is connected thereto. To maximize the space available for containment of a compression spring of sufficient length to function as herein described. the axial bore through the exten-sion element is preferably disposed off-center or asymmetrically of the center of the extension element. To provide even greater space for accommodation of the compression spring; the latch ball and bearing member, the latching bore may be oriented obliquely relative the extension longitudinal axis. Still further optimi-zation of space is achieved by employing a cup-shaped element as the bearing member and wherein an end of the compression spring including several of its helicies is constantly disposed there-within.

Abstract: Broadcast segment recognition systems (10) and methods are provided in which a signature representing a monitored broadcast segment is compared with broadcast segment signatures in a data base (412) representing known broadcast segments to determine whether a match exists. Criteria for determining the validity of such a match are provided. In one aspect, signatures re-presenting audio broadcast signals are formed by comparing temporally displaced portions of respective frequency band values within plural frequency bands of the broadcast audio signal. Systems and methods are provided for producing signatures repres-enting intervals of a video signal which compensate for shifts in an edge of a picture (142) represented by the video signal. In ad-dition, signatures characterizing respective intervals of a broadcast signal exhibiting correlation are produced by generating a dif-ference vector (150) for each respective interval and carrying out vector transformations of the different vectors (150) to reduce such correlation. Moreover, signatures characterizing intervals of a video signal are produced with corresponding mask words re-presenting reliability of values comprising the signature. Mask words of first and second signatures thus formed representing dif-ferent portions of the video signal displaced from one another are compared to establish the values of the mask word.
