A system and method for counting ridges in a captured print image frame is described. A pixel path through the captured print image frame is traversed. A hysteresis band for the pixel path is determined. A number of crossings of the determined hysteresis band is counted while traversing the pixel path. A number of print ridges based on the counted number of hysteresis band crossings is determined.

A first portable messaging unit (PMU) ( ) sends ( ) address information to a second PMU through a wireless messaging system, and the second PMU receives ( ) the address information. In response, the second PMU makes a check ( ) of whether information identical to the address information is stored in its address book ( ) and then processes ( ) the address information in a predetermined manner dependent upon the result of the check.

A server (112) sends (604) selected codebooks (226) and application identifiers (228) to be associated with the codebooks, to a client (122) in preparation for communicating messages. The client receives and stores (606) the selected codebooks and application identifiers. Subsequently, the server, in response to having a message to send to the client, compresses (708) the message according to a codebook associated with an application generating the message, and transmits (710) the message and an application identifier to the client. The client, in response to receiving the message and the application identifier, identifies (714), from the application identifier, the application to receive the message and, hence, the codebook associated with the application, to use for decompressing the message. The client then decompresses (716) the message according to the codebook.

A method (100) for enhanced duplicate message processing at a portable subscriber unit (122) comprises the steps of receiving a first message having a first set of message data and a message sequence number associated with the first message. Then portable subscriber unit receives (402) a subsequent message having the same message sequence number (406) and a subsequent set of message data and creates error indications corresponding to errors detected in the portions of the subsequent set of message data. Then the portable subscriber unit compares (412) the first set of message data and its corresponding error indications with the subsequent set of message data and its corresponding error indications. The subsequent message is then tagged (420) if the subsequent message has less error indications (414) than the first message and if the first message was deleted by the user (418) and if the first message contained an error (426).

A selective call receiving device (10) such as a pager is controlled to dynamically change a base frame assigned to the device and subsequent control frames derived therefrom. The time that the device is operative to look for its address in a received signal can thus be dynamically changed to improve the efficiencies of a mixed systems environment without substantially reducing the battery life of the selective call receiving device (10). In two embodiments of the invention a new base frame for the device is derived from an originally assigned base frame that is stored in the selective call receiving device. In another embodiment, a new base frame for the device is derived from the device's address along with frame management information that is received by the selective call receiving device.

A method (400) for error correction processing of a repeat message in a messaging system where each repeat message contains errors in different portions of the repeat message includes the steps in a portable subscriber unit (122) of receiving a first copy containing a first set of errors (402) and receiving a subsequent copy containing a subsequent set of errors (406). A comparison (410) between the first set and subsequent set of errors is done to eliminate (412) any non-recurring errors in forming an error reduced message. The error reduced message is corrected as necessary if an nth copy of the repeat message is received and if errors remain in the error reduced message by comparing a set of remaining errors in the error reduced message with an nth set of errors found in the nth copy of the repeat message to eliminate any further non-recurring errors.
