Filed: 1992-01-15
Abstract: (54)Title: IMPACT RECOVERY DELINEATION SYSTEM            (57) Abstract An impact recovery delineation system (10) comprises a base mem-ber (12) that provides improved bonding to the road surface, sealed, pneu-matic tube (16) of high impact resistant material composition acts as a de-lineator post and upper (24) and lower (26) load cell elements are provided with cable passages (50 & 52) to allow side-by-side placement of wire rope cables (54 & 56). The passages (50 & 52) are geometrically configured and have radiused (62 & 64) and straight edges (63 & 65) which result in rapid bending and recovery of the delineator post system (10) upon impact. A sig-nage panel (18) has air vents (17) to reduce wind resistance and improve recovery of the impacted system. A safety loop (55) in the cable system pre-vents the delineator post (10) and signage (18) from being separated.

Title: D. c. chopper regulating method and apparatus incorporating bilateral regulating voltage path
Inventor: PHELPS THOMAS K
IPC: H02M7/06
Filed: 1993-01-19
Abstract: D.C. CHOPPER REGULATING METHOD AND APPARATUS INCORPORATING          BILATERAL REGULATING VOLTAGE PATH     ABSTRACT OF THE DISCLOSURE     An unregulated D.C. input voltage (VIN) is processed by a high power chopper (34,36) to produce a first chopped signal having the same voltage as the input (VIN), and by a low power chopper  (56,58)  to produce a second chopped signal in synchronism with and having a lower voltage than the first chopped signal.   The first and second chopped signals are algebraically combined by transformers (52,54) to produce an A.C. output signal which may be converted to D.C. (VOUT). The second chopped signal may be controlled to have the same polarity relative to the first chopped signal in which case the voltages add to increase the output voltage (VOUT), or to have the opposite polarity relative to the  first  chopped  signal  in  which  case  the  voltages subtract to decrease the output voltage (VOUT). The periods of  addition and  subtraction are alternated within the period of the first chopped signal.  The ratio of addition and subtraction of the second chopped signal may be varied to adjust the ratio of output voltage to input voltage over a wide range.  An energy storage inductor (62) is provided in the high power chopper path to average the voltage addition and subtraction.  The high power chopper operation may be intermittently interrupted to limit input current flow during startup, and switches  (102,104) provided to discharge energy stored in the  inductor  (62)  into the transformers (52,54) and thereby contribute to the output voltage (VOUT).

Abstract: A SEQUENTIAL PATTERN MEMORY SEARCHING AND STORAGE MANAGEMENT TECHNIQUE The adaptive sequential pattern memory search technique only examines the contents of a subset of the total number of memory locations in each search for information representative of a character string. The subset includes a plurality of storage locations and each examination is performed in one concurrent read operation. If the character string is not matched, the memory must be updated tostore information representative of the unmatched string. This updating process selects one location from the subset for storing this representative information. Advantageously, an indicator of when each stored representative information lastmatched a character string is maintained and utilized in the selection process. In addition, to avoid operational errors associated with outputting invalid information from the "child" of a previously discarded "parent", an indication of the time each stored entry is created is utilized to remove such invalid information as it is detected in the updating process.
