Patent number: 11241111Abstract: A mail recovery device for insertion into a mailbox, the device structured to adjust to the internal dimensions of the mailbox. A base member of the device rests on top of mailbox bottom surface, a pair of side members are disposed along the side surfaces of the mailbox, and a rear member is disposed along the rear surface of the mailbox. The side members include a plurality of side portions coupled together by a plurality of fold lines, while the rear member includes a plurality of rear portions coupled together by a plurality of fold lines. The fold lines are structured to provide the device with dimensional flexibility so that the size of the mail recovery device may be adjusted to the mailbox internal dimensions.Type: GrantFiled: January 31, 2020Date of Patent: February 8, 2022Inventor: Mark McHenry

Patent number: 8997170Abstract: A device is disclosed that includes software components for executing actions and for controlling the device in order to conform to specified policies. The device includes a controller to deny or permit execution of actions. The controller monitors and interrupts execution of device's actions in order to determine whether an action violates a policy, policy rules, or if the action is prohibited by a policy. The controller also manages policies defined for the device. Each policy is translated into a language understandable by the controller and stored on the device. Each policy can be updated or changed dynamically. Additionally, each policy can securely be updated or changed remotely.Type: GrantFiled: April 10, 2007Date of Patent: March 31, 2015Assignee: Shared Spectrum CompanyInventors: Filip Perich, Mark A.

Patent number: 8793791Abstract: A method for classifying a signal is disclosed. The method can be used by a station or stations within a network to classify the signal as non-cooperative (NC) or a target signal. The method performs classification over channels within a frequency spectrum. The percentage of power above a first threshold is computed for a channel. Based on the percentage, a signal is classified as a narrowband signal. If the percentage indicates the absence of a narrowband signal, then a lower second threshold is applied to confirm the absence according to the percentage of power above the second threshold. The signal is classified as a narrowband signal or pre-classified as a wideband signal based on the percentage. Pre-classified wideband signals are classified as a wideband NC signal or target signal using spectrum masks.Type: GrantFiled: November 1, 2011Date of Patent: July 29, 2014Assignee: Shared Spectrum CompanyInventors: Eugene Livsics, Mark A McHenry, Dmitry Dain, Karl Steadman, Olga Ritterbush

Patent number: 8559301Abstract: Methods for using a detector to monitor and detect channel occupancy are disclosed. The detector resides on a station within a network using a framed format having a periodic time structure. When non-cooperative transmissions are detected by the network, the detector assesses the availability of a backup channel enabling migration of the network. The backup channel serves to allow the network to migrate transparently when the current channel becomes unavailable. The backup channel, however, could be occupied by another network that results in the migrating network interfering with the network already using the backup channel. Thus, the detector detects active transmission sources on the backup channel to determine whether the backup channel is occupied. Methods for using the detector include scheduling detection intervals asynchronously. The asynchronous detection uses offsets from a reference point within a frame.Type: GrantFiled: September 9, 2011Date of Patent: October 15, 2013Assignee: Shared Spectrum CompanyInventors: Mark A.

Publication number: 20070263566Abstract: A method and transceiver for determining spectrum availability within a give area is disclosed. The given area includes cells in a grid. A belief evaluator receives a measurement from a signal and assigns an instantaneous belief indicator, an instantaneous disbelief indicator and an instantaneous ignorance indicator based on a detection threshold and the power level of the measurement. The indicators quantify the probability of a presence of a transmitter within the grid cell. A belief accumulator uses the instantaneous indicators along with accumulated belief, disbelief and ignorance indicators from previous measurements to determine cumulative belief, disbelief and ignorance indicators. The accumulated belief, disbelief and ignorance indicators are the results of previous measurements and belief/disbelief/ignorance determinations for the grid cell. An allocator indicates the status of the grid cell and whether a spectrum is available.Type: ApplicationFiled: May 12, 2006Publication date: November 15, 2007Inventors: Mark McHenry, Alexe Leu
