Patent number: 9300351Abstract: A method significantly reduces the average power for radio communication in a communication system, such as a system that has applications requiring low communication latency. The method may use a low power radio communication circuit (e.g., a non-heterodyne receiver) to wait for a communication request, taking advantage of the low power consumption of the radio communication circuit. Subsequent to receiving and validating the communication request, the communication system may switch to a more efficient—but higher power—communication circuit. Thus, effective communication is achieved without making undesirable tradeoffs, such as reduced sensitivity.Type: GrantFiled: September 11, 2014Date of Patent: March 29, 2016Assignee: SecureALL CorporationInventor: Arun Kumar Sharma

Publication number: 20140159383Abstract: A sensing system senses whether or not a lock's bolt (140), e.g. deadbolt, is aligned with a hole (150) which the bolt is to engage in the locked state. In electronic locks, the bolt is not driven into the hole until the sensing system indicates that the bolt is aligned with the hole. Another sensing system senses the position of the bolt and/or a dead-latch bar (1310). This sensing system is spaced from the bolt's end engaging the hole in order not to interfere with the alignment sensing. The two sensing systems are used to determine whether the lock is locked or unlocked. A magnet system provides alignment assistance to align the bolt with the hole before the bolt is driven into the hole. Position encoding for lock and non-lock devices, and other features and embodiments are also provided.Type: ApplicationFiled: February 12, 2014Publication date: June 12, 2014Applicant: SecureALL CorporationInventors: Arun Kumar Sharma, David Arthur Candee

Patent number: 8606215Abstract: A radio device and a method to operate a non-heterodyne receiver are provided. The radio device is configured to receive a signal waveform and to provide a wake-up signal to a second communication circuit when the signal waveform is a valid communication request; wherein the second communication circuit switches from a power saving state to an operating state upon receiving the wake-up signal from the non-heterodyne receiver. The non-heterodyne receiver further including an Electromagnetic interference (EMI) rejection circuit, including a narrow band filter and a broadband filter to reject an EMI signal. A filter circuit for a narrow passband circuit is also provided. The filter including a buffer circuit; a crystal oscillator coupled to the output of the buffer circuit; and an inverting amplifier coupled in parallel to the crystal oscillator.Type: GrantFiled: January 26, 2012Date of Patent: December 10, 2013Assignee: SecureALL CorporationInventor: Arun Kumar Sharma

Patent number: 8559642Abstract: A mobile device (110), e.g. a token, holds a current key and one or more previous (expired) keys in memory (130). If the token needs to communicate with another device (144), e.g. with a reader, and the reader does not have the current key but has a previous key, the token encrypts the current key with the previous key and sends the ciphertext to the reader, which decrypts the current key. The token use different cryptographic material for communication with respective different facilities. Rather than requesting the reader to identify the facility, the token assumes that the facility is the same as in the most recent successful authentication. If the authentication fails, only then the token requests the reader to identify the facility. Authentication time and electric power are saved if the facility is the same. Other embodiments are also provided.Type: GrantFiled: December 28, 2011Date of Patent: October 15, 2013Assignee: SecureALL CorporationInventor: Michael Wurm

Patent number: 7446644Abstract: Methods and systems are provided for a universal key that enables a user to have access to any type of secured portal, both physical and electronic, in a wireless, hands-free, distance-independent manner without requiring contact or line of sight access between the key and the secured portal. The universal key is not distance-dependent, and each secured portal can be provided with its own prescribed activation range, if desired. Some portals may be provided with long range activation, such as 50 feet, while other portals may be provided with short range activation of a few feet or less. The type of portal being secured and the range of activation may be selected by the user and is not limited by the universal key. In addition, the universal key will provide access to the secured portals in a hands-free fashion so that the user need not push any buttons or take any other action in order to obtain access to the portal.Type: GrantFiled: January 14, 2005Date of Patent: November 4, 2008Assignee: SecureAll CorporationInventors: Richard A.
