摘要： A chainsaw guide bar includes a bar body and a nose member removably attached to the bar body by an elastic snap-in coupling, eliminating the need for separate fastening elements. The snap-in coupling includes dimples formed in tongues of the nose member, the dimples being received in holes formed in a web of the bar body. The dimpled portions of the tongues are elastically flexible in a thickness direction of the guide bar to enable the nose member to be inserted or removed.

摘要： A method and apparatus for automatic gain control of a receiver provides compensation of gain control operations for received signal disruptions. In one embodiment, an automatic gain control circuit remembers control state information from a time just before a given disruption, and uses it to reset the automatic gain control circuit at the end of the disruption, or to maintain the automatic gain control circuit during the disruption. The remembering function may be triggered, such by detecting an impending disruption, or done periodically at a high enough update rate that the remembered information is always current with respect to any given disruption. Thus, an exemplary automatic gain control circuit may generate a receiver gain control signal by filtering received signal power measurements, and compensate the generation of that gain control signal by capturing filter state information just prior to signal disruptions. Compensation may comprise resetting or freezing the filter.
摘要翻译：用于接收机的自动增益控制的方法和装置提供对接收信号中断的增益控制操作的补偿。在一个实施例中，自动增益控制电路从给定中断之前的时间内记住控制状态信息，并且在断层结束时使用它来复位自动增益控制电路，或者在中断期间维持自动增益控制电路。可以触发记忆功能，例如通过检测即将发生的中断，或者以足够高的更新速率周期性地完成记忆功能，使记忆信息相对于任何给定的中断始终是最新的。因此，示例性的自动增益控制电路可以通过滤波接收的信号功率测量来产生接收机增益控制信号，并且通过在信号中断之前捕获滤波器状态信息来补偿该增益控制信号的产生。补偿可能包括重置或冻结过滤器。

摘要： An insect exterminating device which is characterized in a first embodiment by a handle having a handle base attached to a downwardly-extending probe frame fitted with a bracket and a spring for receiving an aerosol or pressurized fluid canister containing an insect treatment fluid. A probe projects from the probe frame and a spring-loaded activator button is provided on the handle base for activating the pressurized fluid canister valve to dispense the treatment fluid from the canister, through passages provided in the activator button, the handle base, the probe frame and the probe, into an insect bed. In a preferred embodiment the bracket is adjustable for accommodating pressurized fluid containers of various length. In a second embodiment the fluid canister is seated on a spring in a round frame and the treatment fluid is dispersed from the canister through a tube to the probe by pressing a spring-loaded activator button. In both embodiments the spring-loaded activator button acts as a valve to facilitate depression and dispensing treatment fluid from the pressurized fluid container on demand.
