Abstract: Methods and systems of correcting operation of multiple modules are described. The methods include generating a first dual-tone signal in a first module and transmitting the first dual-tone signal to a second module. A second dual-tone signal is generated in the second module and transmitted to the first module. The first module determines a first phase of the received second dual-tone signal and the second module determines a second phase of the received first dual-tone signal. Operation of one or both of the first and second modules is corrected based on the determined first phase and the determined second phase.

Abstract: When combined with a metal point, this ten inch plastic pistol crossbow bolt is designed to extend past the barrel of a pistol crossbow so it can be used for small game hunting, pistol crossbow fishing, recreational shooting and competition shooting. The major fault of the standard bolt commonly used with a pistol crossbow is, they are less than seven inches in length and do not extend past the end of a pistol crossbow barrel. Therefore, their use is limited to target points and recreational shooting only. Other faults of the standard short bolts are their high travel speed. They are very difficult to be viewed in flight, causing most bolts to be lost after one use. Also, because of their irretrievability from any commonly used target, they cannot be found and scored in any type of shooting competition. This ten inch bolt is a solid one piece unit made of a strong but, light weight plastic compound. It has a NOCK to securely hold the bow string in place. Standard pistol crossbow bolts do not have a nock.

Abstract: When combined with a metal point, this ten inch plastic pistol crossbow bolt is designed to extend past the barrel of a pistol crossbow so it can be used for recreational shooting, competition shooting, small game hunting, pistol crossbow fishing and pistol crossbow scuba fishing. The main fault of the standard pistol crossbow bolt is they are less than seven inches in length and do not extend past the end of a pistol crossbow barrel. Therefore, their use is limited to target points and recreational shooting only. Other faults of the standard short pistol crossbow bolts are their high travel speed. They are very difficult to be viewed in flight, causing most bolts to be lost after one use. Also, their irretrievability from any commonly used target.

Abstract: An off-duty scheduling system for police officers automatically generates a list of qualified available officers. Filtering eliminates, from the candidate pool, officers lacking requisite training or credentials, officers who have reached or exceeded off-duty work limits, and inactive officers. Multi-level sorting arranges the candidate pool in order of priority based upon specified criteria, such as, time from last off-duty assignment and seniority. Officers are invited to perform the job, until the job is fully staffed. Start and end of job performance are tracked and reported, with payments made automatically upon completion.

Abstract: Methods and systems of correcting operation of multiple modules are described. The methods include generating a first dual-tone signal in a first module and transmitting the first dual-tone signal to a second module. A second dual-tone signal is generated in the second module and transmitted to the first module. The first module determines a first phase of the received second dual-tone signal and the second module determines a second phase of the received first dual-tone signal. Operation of one or both of the first and second modules is corrected based on the determined first phase and the determined second phase.
