20080259552 | Wearable Component with a Memory Arrangement - A system may include (a) a holder including a wearable component, (b) a dock coupled to the wearable component; (c) a memory coupled to the dock; and (d) a computing device removeably coupled to the dock. The computing device receives from and stores data to the memory. The data is capable of causing the coupled computing device to automatically adopt a mode of another computing device coupled to the dock at a different time. | 10-23-2008 |
20090058599 | Customizable Mechanically Programmable RFID Tags - A system and method to track a status an item, or steps in a process, via one or more mechanical modifications to an RFID tag. In one embodiment, a plurality of tearable strips are attached to the tag, each strip having an electrical conductor. Each tearable strip may receive a visual or tactile indicia, such as text, a color code, a graphic symbol, or a tactile indicator (such as Braille) to assign a meaning to the strip, where the meaning is associated with the status or condition of the item, or the stage, step, or status or the process. By tearing some strips or all strips, a desired bit pattern may be programmed into a register of the RFID tag. The bit pattern may reflect the status or condition of the item, or the stage, step, or status of a process. | 03-05-2009 |
20090079571 | Optimizing RFID Reader Duty Cycle Or Power To Preserve Battery Life - The duty cycle of a portable battery-powered RFID tag reader is reduced during time periods when it is less likely to produce a “read” in order to preserve battery life. The reader operates with an aggressive duty cycle during periods of a high probability of a tag read and reduces duty cycle during periods of a low probability of a tag read. In this manner a user does not perceive the reader to be sluggish. An alternative embodiment reduces peak operating power during time periods when a tag is less likely to produce a “read” in order to preserve battery life. | 03-26-2009 |
20090115666 | Multi-Functional External Antenna - A mobile device with a multi-functional external antenna comprises a housing and an external antenna. The external antenna is disposed at least partially on the housing and conforms to the housing. The external antenna is configured to one of receive wireless data signals and transmit wireless data signals. The external antenna is further configured to conduct power signals. | 05-07-2009 |
20090153319 | RFID Reader/Interrogator Sub-Band Selection - Due to design constraints and installation variability, RFID interrogator antennas do not always function optimally across the entire channel on which they are intended to operate due to diminished antenna bandwidth. Techniques are described for selecting a sub-band of frequencies within the channel on which a particular RFID interrogator can be operated to enhance operating efficiency. These techniques include a VSWR measurement technique and a read/no read technique are disclosed for identifying a useful sub-band of frequencies. The operation of a reader/interrogator is then limited to an identified sub-band so that an RFID interrogator/tag system can be operated efficiently. | 06-18-2009 |
20090160611 | Enhanced Communication Via RFID Interrogator - An RFID portal is enhanced to provide communication capability to RFID communication enabled devices. Such devices include cameras, PDAs, voice communicator, keyboards, displays, indicators, storage devices, etc. Devices are made RFID communication enabled by providing them with an RFID interface and an RFID tag “front end”. Such an enhanced device communicates with an enhanced portal via an RFID reader/interrogator associated with the portal. The portal may have connection to other communication channels, such as an Ethernet tie to a network, a landline phone connection, a cellular interface, an 802.11 connection, a Bluetooth channel, etc. Such connections allow an RFID communication enabled device to communicate beyond the enhanced portal to the outside world. | 06-25-2009 |
20090160645 | Voice Over RFID - A wearable mobile computer communicates with a headset worn by an operator using a communication channel established between the computer and a radio frequency identification (“RFID”) tag located in the headset. The headset may be configured for receive only (voice travels only from the computer to the headset) or configured for two-way voice communication. For two-way communication backscatter from the RFID tag is used to carry voice signals. | 06-25-2009 |
20090174361 | Energy Harvesting In RFID Systems - Methods, systems, and apparatuses for providing power to devices that are part of RFID systems are described. Energy is harvested at portable/mobile devices, stored and conditioned to provide on-going power as needed for various circuits/components. The energy may be generated in a variety of ways, including using a vibratory energy harvesting device, a magnetic energy harvesting device, and an optical energy harvesting devices. | 07-09-2009 |
20100019731 | Device and Method for Instantaneous Load Reduction Configuration to Prevent Under Voltage Condition - A device may include a battery and a plurality of components receiving power from the battery. A voltage of the battery is maintained above a threshold voltage by decreasing a current drawn by one of the components when the battery voltage approaches the threshold voltage. | 01-28-2010 |
20100020971 | Device and Method for a Secure Transaction - A device comprises a first processor and a second processor. The first processor is connected to a display, a data input arrangement, and a data acquisition device in a first mode of operation. The first mode of operation relates to performing non-secure operations. The second processor is connected to the display, the data input arrangement, and the data acquisition device in a second mode of operation. The second mode of operation relates to performing a secure operation. The secure operation relates to a sales transaction. When the device is in the second mode of operation, the data acquisition device receives secure data from a remote source. The secure data is forwarded to the second processor to determine a success of the sales transaction. | 01-28-2010 |
20100026455 | Device and Method for Reducing Peak Current Demands In a Mobile Device - A device may include a battery; a first component drawing a first current from the battery, the first current being below a threshold; and a second component drawing a second current from the battery. The second component indicates the entering of a low current mode for a predetermined time. The first component is allowed to draw a third current above the threshold for the predetermined time. | 02-04-2010 |
20110124363 | SETTING SAR EXPOSURE LIMIT OF MOBILE DEVICES - A programmable controller and software that monitors periods an RF transmitter is active and a output power level during those periods of activity. These two values are multiplied together and accumulated over time to provide a value for the RF emissions for some period. A limit is set for the RF emissions for any period and if the RF emissions exceeds (or is expected to exceed given the current rate) the set limit, the system limits the subsequent emissions to not exceed the set limit. This reduction in emissions rate come at the cost of a small performance reduction. | 05-26-2011 |
20140045515 | REAL-TIME PLANOGRAM GENERATION AND MAINTENANCE - Generating a planogram of a facility in real-time, includes positioning a wireless mobile device at a plurality of geometric positions within the facility. A location of the mobile device at each position is then established using a location mechanism. Each geometric position is then associated with that location of the mobile device. The planogram is then updated with information about the geometric position. The geometric positions are associated with physical objects modeled in the planogram. Non-geometric information can also be obtained at the location of the mobile device, and this non-geometric information can be overlaid onto the planogram. | 02-13-2014 |
