Patent number: 9281707Abstract: Described is a system and method for charging a battery. The system includes a processor powered by a battery; and a controller determining a remaining battery charge of the battery. The controller sets a first charge current to recharge the battery when the remaining battery charge is insufficient to operate the processor. The controller wakes the processor when the battery has been recharged so that the remaining battery capacity is sufficient to operate the processor. The processor negotiates for a second charge current to recharge the battery. The controller sets the second charge current when the processor successfully negotiated.Type: GrantFiled: July 24, 2012Date of Patent: March 8, 2016Assignee: Symbol Technologies, LLCInventors: Kevin Cordes, Christopher R.

Patent number: 7498766Abstract: Described is a system and method for authenticating a power source. The system comprises a battery including a first encryption engine storing a first key, and a battery charger including a microcontroller and a second encryption engine storing a second key. When the microcontroller detects a coupling of the battery to the charger, the microcontroller issues a challenge to the first encryption engine and the second encryption engine. The first encryption engine generates a first response as a function of the challenge, the first key and a predefined algorithm, and the second encryption engine generates a second response as a function of the challenge, the second key and the predefined algorithm. The microcontroller compares the first and second responses to authenticate the battery.Type: GrantFiled: May 30, 2006Date of Patent: March 3, 2009Assignee: Symbol Technologies, Inc.Inventors: Christopher R.

Patent number: 6351214Abstract: A method and a device for detecting the breakage of glass. A glass breakage detector that uses an acoustic transducer, an analog-to-digital converter, and a processing means which uses software algorithms to determine if a signal received by the acoustic transducer is a result of glass breaking. The glass breakage detector also uses amplifiers which have a greater gain response for higher frequency components in the received signal. The glass breakage detector is also able to correct the offset error generated by the amplifiers. The processing means or digital signal processor (DSP) uses a feature extraction software algorithm that extracts characteristics of the received sound using a plurality of filters centered at different frequencies and a rules analysis software algorithm to compare the extracted features to features from glass breakage and false alarms. The DSP is also capable of transmitting the extracted features to an external computing device for further analysis.Type: GrantFiled: April 9, 2001Date of Patent: February 26, 2002Assignee: Pittway Corp.Inventors: Kenneth G.
