Title: Digital receiving apparatus
Inventor: FUTAGI SADAKI
IPC: H04B1/707
Filed: 1998-08-19
Abstract: De-spread sections 35A, 35B, and 35C de-spread received multipath signals 30 based on time data 34A, 34B, and 34C, and output de-spreading signals 36A, 36B, and 36C to a weighting circuit 37, respectively. The weighting circuit 37 performs a threshold determination using an absolute value of the de-spreading signals 36A, 36B, and 36C.  When each of the de-spreading signals is below a certain threshold value, a weighting factor is set to 0. When each of the de-spreading signals is more than the threshold value, a complex conjugate of phase data of the de-spreading signals 36A, 36B, and 36C is used as a weighting factor. The de-spreading signals 36A, 36B, and 36C are  multiplied  by  the  corresponding  weighting  factor, respectively.

Title: Time period inventory management system
Inventor: FOX BILLY SHANE
IPC: G06Q30/00
Filed: 1998-12-18
Abstract: A method for selecting an optimum time period from an inventory of available time periods, where each time period has a predetermined duration including selected and unselected time portions and an associated cost includes determining the total amount of time in each time period and the total amount of unselected time in each time period. A calculation is made for each time period to generate an inventory utilization index ratio based upon the total amount of time in each time period divided by the total amount of unselected time remaining in each time period. A table is prepared for all time periods in the inventory ranked numerically by the inventory utilization index ratio. A cost range is determined for each of the costs associated with each of the time periods. The table of time periods in the inventory is revised by removing time periods from the inventory which are not within the desired cost range. A time period is selected from the table based upon the ranking of the time period. Information related to the selected time period is stored as containing selected time in the time period inventory.
