Abstract: Systems and methods for shipping a package from a package sender to an intended recipient, utilizing Internet communications to place shipping orders, request on demand package pickup, maintain and utilize pre-stored profile information, view shipping history, track orders, etc. A package sender with an Internet-accessible computer accesses an Internet site and associated shipping system operated by a shipping service provider. The package sender enters information required for shipping the package, including shipping options and methods for payment, and the shipment transaction is validated. If the transaction is validated, printer indicia are communicated to the customer's computer, which is enabled to locally print a prepaid label containing special machine-readable as well as human-readable indicia.

Abstract: An autostereoscopic steering light-guide three-dimensional display. The display includes a light modulator, a light guide in light-transmitting orientation to the light modulator, a light source in light-transmitting orientation to the light guide, and a control element adjacent the light guide. The control element is responsive to a first command to cause the light guide to steer light from the light source in a first direction through the light modulator and responsive to a second command to cause the light guide to steer light from the light source in a second direction through the light modulator.

Abstract: A Global System for Mobile (GSM) cellular system transceiver with time division duplexed operations for receiving a data signal, monitoring received signal strength and transmitting a data signal during a single time frame. Multiple data registers are used to store the phase lock loop (PLL) frequency control data, e.g., during the last time slot (slot 7) of the prior time frame (or elsewhere in the prior time frame where time permits). Also during slot 7 of the prior time frame, the PLL is programmed using the first data set for the data reception operation to be performed during one or more of the initial time slots (e.g., time slots 0-3) of the present time frame. During the next time slot (e.g., slot 4), the PLL is programmed using the second data set for the signal strength monitoring operation to be performed during that same time slot. During the next time slot (e.g.
