Patent number: 11037092Abstract: A computer-implemented method for managing a product delivery process, according to one embodiment, includes receiving status information about a product container that contains a food product. The status information includes sensor-derived conditions of the product container including at least a temperature in the product container. Preferred ranges for the conditions of the product container are determined based on a profile associated with the food product stored therein. A determination is also made as to whether the received conditions from the product container are within the preferred ranges. A command is sent in response to determining that at least one of the received conditions is and/or has been outside the preferred range associated therewith for a predetermined amount of time.Type: GrantFiled: March 21, 2019Date of Patent: June 15, 2021Assignee: ZEST LABS, INC.Inventors: Peter A. Mehring, Thomas C. Reese, Dean M. Kawaguchi, Sameer Dekate, Russell Shikami

Patent number: 11037093Abstract: A computer-implemented method for managing a food delivery process, according to one embodiment, includes receiving a food product history for each type of food product stored in each of a plurality of product containers. At least one of the food products is predestined for a first destination that is different than a second destination of another of the food products. Each food product history includes: an expiration date of the associated food product, storage time information, storage condition information, and temperature history. The food product history is used to determine a prioritized delivery scheme for the product containers. The prioritized delivery scheme is sent to an individual transporting the product containers and/or to a dispatcher.Type: GrantFiled: March 21, 2019Date of Patent: June 15, 2021Assignee: ZEST LABS, INCInventors: Peter A.

Patent number: 11037094Abstract: A computer-implemented method for generating a report about a food product delivery process, according to one embodiment, includes receiving status information about a product container that contains a food product at different times as the product container travels from an origin to a destination. The status information includes sensor-derived conditions in the product container including at least temperature. The status information is stored. The performance of entities involved in delivery of the food product are analyzed relative to ideal handling or process conditions for the type of food product from the origin to the destination using the status information. A report of results of the analysis is output.Type: GrantFiled: March 21, 2019Date of Patent: June 15, 2021Assignee: ZEST LABS, INC.Inventors: Peter A. Mehring, Thomas C. Reese, Dean M.

Patent number: 10423918Abstract: A computer-implemented method according to one embodiment includes receiving, by the computer, status information about one or more product containers, wherein the status information includes conditions of each of the one or more product containers. Preferred ranges for the conditions of each of the one or more product containers are determined based on food products stored in the one or more product containers, where the preferred ranges change over time by a predefined amount per unit time, and where the predefined amount and the unit time are specified in a profile associated with products stored in the one or more product containers. A determination is made as to whether the received conditions from the one or more product containers are within the preferred ranges. A first command is sent in response to determining that at least one of the received conditions is outside the determined preferred range.Type: GrantFiled: March 21, 2019Date of Patent: September 24, 2019Assignee: ZEST LABS, INC.Inventors: Peter A.

Patent number: 6169769Abstract: A method and apparatus for bias suppression which includes a transmitter having a bias suppression encoder and a closed-loop VCO FM modulator and a receiver having a bias suppression decoder and an AC coupled FM demodulator. The bias suppression encoder generates a running sum of an encoded digital data signal as well as the sum of an (N+1)-bit block of an injected digital data signal such that the encoder may invert a block of (N+1)-bits of the injected data signal if both sums are of the same polarity thereby reducing the average DC bias of the encoded digital data signal. The encoded data signal is modulated using a closed-loop VCO FM modulator with the DC tracking effect minimized as compared to modulating the non-encoded signal directly. In the receiver having an AC coupled FM demodulator, the bias suppression decoder extracts a stuff bit set by the transmitter and inverts the received block of data if the stuff bit is true.Type: GrantFiled: May 13, 1998Date of Patent: January 2, 2001Assignee: Symbol Technologies, Inc.Inventor: Dean M.

Patent number: 5754587Abstract: A method and apparatus for bias suppression which includes a transmitter having a bias suppression encoder and a closed-loop VCO FM modulator and a receiver having a bias suppression decoder and an AC coupled FM demodulator. The bias suppression encoder generates a running sum of an encoded digital data signal as well as the sum of an (N+1)-bit block of an injected digital data signal such that the encoder may invert a block of (N+1) -bits of the injected data signal if both sums are of the same polarity thereby reducing the average DC bias of the encoded digital data signal. The encoded data signal is modulated using a closed-loop VCO FM modulator with the DC tracking effect minimized as compared to modulating the non-encoded signal directly. In the receiver having an AC coupled FM demodulator, the bias suppression decoder extracts a stuff bit set by the transmitter and inverts the received block of data if the stuff bit is true. Alternately, the received data block is not inverted if the stuff bit is false.Type: GrantFiled: February 15, 1996Date of Patent: May 19, 1998Assignee: Symbol Technologies, inc.Inventor: Dean M.
