Publication number: 20230079803Abstract: A waste treatment includes a package with compartments. A surfactant, an oxidizing agent, and, optionally, a liquid may be disposed within the compartments. The oxidizing agent is within a compartment that does not contain the surfactant or the liquid. A bursting force may unseal a sealed end of each compartment. The liquid flushes the surfactant and the oxidizing agent out of the package into a non-contact agitating toilet. A dual compartment package made with a fluidly disintegrable material may separate the surfactant from the oxidizing agent where the liquid may not be provided. The waste treatment may be mixed with a waste deposited within the non-contact agitating toilet. The package may disintegrate in the presence of the liquid to allow the reactive components to mix. A plurality of waste treatments may be connected. A perforated barrier may separate a first waste treatment from a second waste treatment.Type: ApplicationFiled: August 17, 2022Publication date: March 16, 2023Applicant: Coversan, LLCInventor: Curtis Randall Hibbs

Publication number: 20220380239Abstract: A method for waste material treatment that results in a more stable, entombed treated waste product. A reactive treatment formulation can be dispensed with a waste material deposit into a self-contained non-contact agitating toilet to form a stabilized viscous mass. The reactive treatment formulation mixed with the waste material deposit prevents odors, bacterial growth, and stabilizes the waste material into a treated waste product to reduce spillage during disposal.Type: ApplicationFiled: August 8, 2022Publication date: December 1, 2022Applicant: Coversan, LLCInventor: Curtis Randall Hibbs

Patent number: 11011198Abstract: A tape drive may arrange timing-based-servo marks into a timing-based-servo pattern. The timing-based-servo pattern may be at least one M-pattern. The tape drive may select the at least one M-pattern. The tape drive may match at least two timing-based-servo marks in the at least one M-pattern. The tape drive may determine, from the matching, whether an alignment of the at least two timing-based-servo marks is demonstrative of tape-creep.Type: GrantFiled: October 29, 2019Date of Patent: May 18, 2021Assignee: International Business Machines CorporationInventors: Daniel James Winarski, Nhan Xuan Bui, Lee Curtis Randall, Richard Bradshaw

Patent number: 10964350Abstract: A method includes determining whether a tunneling magnetoresistance (TMR) sensor is corroded using resistance, amplitude and signal to noise ratio (SNR) measurements of the sensor. A method to determine whether a TMR sensor is corroded includes determining an expected initial resistance value, RTMRoUse and measuring a resistance value, RTMR, of the sensor. The method includes calculating a ratio of the RTMR value and the expected initial resistance value, RTMRoUse and determining whether the ratio is in a predefined range for the TMR sensor. In response to determining that the ratio of the sensor is within the predefined range, the method includes outputting an indication that the TMR sensor is corroded. In response to determining that the ratio of the sensor is outside the predefined range, the method includes outputting an indication that the TMR sensor is not corroded.Type: GrantFiled: July 9, 2019Date of Patent: March 30, 2021Assignee: International Business Machines CorporationInventors: Icko E.

Patent number: 10952572Abstract: A toilet apparatus has a waste material receiving bowl with an opening at a top of the waste material receiving bowl. A bag receives and retains waste material and an absorbent media introduced through the opening. An agitation device agitate the absorbent media and the waste material at a lower portion of the bag to cause the absorbent media to at least substantially cover the waste material while the agitation device is not contacting the absorbent media and the waste material.Type: GrantFiled: November 20, 2019Date of Patent: March 23, 2021Assignee: Coversan, LLCInventor: Curtis Randall Hibbs

Patent number: 10930309Abstract: A tape drive may calculate the slopes for three successive timing-based-servo marks in a timing-based-servo group. The timing-based-servo marks may be arranged in a one or more M-patterns. The three successive timing-based-servo marks may be across the one or more M-patterns. The tape drive may perform a parabolic fit of a gradient of the slopes. The tape drive may determine whether the gradient is demonstrative of tape-creep.Type: GrantFiled: October 29, 2019Date of Patent: February 23, 2021Assignee: International Business Machines CorporationInventors: Daniel James Winarski, Nhan Xuan Bui, Lee Curtis Randall, Richard Bradshaw

Patent number: 10832715Abstract: A tape drive may calculate a slope for each of the timing-based-servo marks in a timing-based-servo group. The timing-based-servo marks are arranged in one or more M-patterns. The tape drive may average the slope for each of the timing-based-servo marks across the one or more M-patterns. The tape drive may generate a least-squares assessment of the averaged slope. The tape drive may determine, from the least-squares assessment, whether the averaged slope is demonstrative of tape-creep.Type: GrantFiled: October 29, 2019Date of Patent: November 10, 2020Assignee: International Business Machines CorporationInventors: Daniel James Winarski, Nhan Xuan Bui, Lee Curtis Randall, Richard Bradshaw
