    • A method of creating a database of poor coverage areas (120) in a wireless communication system includes (100) determining if a signal quality metric (204) of a communication link (130) in a poor coverage area (120) is below a signal quality threshold (202) then incrementing a poor coverage area counter (210), if not, incrementing a good coverage area counter (212). Storing one or more previous coverage areas (138-140) traversed by wireless device (102) prior to entering the poor coverage area (120) and calculating a trajectory (136) to the poor coverage area (120) based on one or more previous coverage areas (138-140) and poor coverage area (120). Subsequently, anticipating entry of the wireless device (102) into the poor coverage area (120) utilizing the trajectory (136) to the poor coverage area (120) and alerting a user of wireless device (102).

    • An improved system and procedure for allowing participants within a group conversation on a wireless communication network to at least temporarily break away from a group conversation and hold a side bar conversation. The side bar conversation may comprise several different types, including a public conversation (much like the original group conversation) or may constitute a private conversation (much like a standard phone call) or private text messaging or data exchange. A group conversation user wishing to hold the side bar conversation uses his user interface to alert other group conversation user(s) with whom he would like to hold the side bar conversation. Either the initiating user or the recipient user(s) can recommend the type of side bar conversation to be had using their user interfaces. If the side bar conversation is a voice conversation, the original group conversation can still be audible in the back ground, but can be reduced in volume relative to the side bar conversation or squelched in and out when the side bar conversation is active. If desired, side bar participants can rejoin the original group conversation by selecting such an option from their user interfaces.
    • 一种改进的系统和程序,用于允许无线通信网络上的群组对话内的参与者至少暂时脱离群组对话并保持侧栏对话。 侧栏对话可以包括几种不同的类型,包括公共对话(非常类似于原始组对话),或者可以构成私人对话(非常像标准电话)或私人文本消息或数据交换。 希望保持侧栏对话的小组会话用户使用他的用户界面来提醒与他想要进行侧栏对话的其他群组会话用户。 发起用户或收件人用户可以推荐使用其用户界面的侧栏对话的类型。 如果侧栏对话是语音对话,则原始组对话仍然可以在背景中听到,但是当侧栏对话激活时,可以相对于侧栏对话减少体积或者在侧栏对话中被压入和移出。 如果需要,侧栏参与者可以通过从其用户界面中选择这样的选项来重新加入原始组对话。

    • Disclosed is a storage container enclosing a plurality of spools for receiving filament such a fishing tippet line. The spools are positioned adjacent to each other on separate shafts and rotate independently. Each spool may be removed from its shaft in the container, and a length of tippet line may be conveniently wound around each spool outside of the container. The spools are then returned to their respective shafts in the container. The free end of each spooled tippet line is threaded through an access hole in the side of the container and extends across the outside of the storage container to a structure that conveniently holds and cuts the tippet line. A desired length of tippet line may be withdrawn through the access hole and cut. The storage container is preferably relatively thin and compact. It may be small enough to fit within an average-sized pocket in a fisher's clothing. When the lid of the storage container is closed, the lines on the spools are protected from tangling and unwinding.
    • 公开了一种封闭多个用于接收细丝的线轴的储存容器,所述丝线是这样的钓竿线。 卷轴在独立的轴上彼此相邻定位并独立旋转。 每个卷轴可以从其容器中的轴上移除,并且一定长度的提拉线可以方便地卷绕在容器外部的每个卷轴上。 然后将线轴返回到容器中各自的轴上。 每个假动提示线的自由端穿过容器侧面的通孔,并延伸穿过储存容器的外部,形成一种方便地保持和切割提拉线的结构。 所需长度的提升线可以通过进入孔被抽出并切割。 存储容器优选地相对薄且紧凑。 它可能足够小,以适合在渔民服装的平均大小的口袋里。 当储存容器的盖子关闭时,线轴上的线条被保护以免缠绕和退绕。

    • A telematics communication system (100) receives an input supply voltage (Vin) (122) from a battery (102) charged by an alternator (101) in an automotive vehicle. The telematics communication system (100) includes a transceiver (104) having a transmitter (107) and a variable delta voltage tracking regulator (VDVTR) (109). The VDVTR (109) provides a regulated output supply voltage (Vout) (124) to a power amplifier (114) in the transmitter (107) responsive to the input supply voltage (122) and a regulator control voltage (TX_EN) (123). The VDVTR (109) has a first operating stage and a second operating stage, each controlled by a bias circuit (R1, R2 and R3), and a third operating stage, controlled by a voltage limiting circuit (D1) to eliminate alternator whine noise (405) that appears on the input supply voltage (122) and, in turn, appears on the regulated output supply voltage (Vout) (124).
