Patent CA-3006438-A1 (CA)
Inventor: FARKAS ALEXANDER T
IPC: H01Q9/42
Filed: 2016-11-23
Abstract: Systems and methods improve tracking performance of an ultra-wide-band (UWB) tracking tag positioned on a player on a sporting field. A UWB antenna is formed with power radiated disproportionately in forward and backward directions as compared to sideways. The UWB tracking tag is aligned with the UWB antenna when positioned on the player such that less power is absorbed by the player than radiated away from the player. The UWB antenna is monopole and may be folded from a single metal sheet forming: a flat top; a first side folded at an acute angle from one edge of the top; a second side folded at an acute angle from another edge of the top; a first solder tab folded at an obtuse angle from the first side; and a second solder tab folded at an obtuse angle from the second side, to join in parallel with the first solder tab.

Title: Arsenic speciation and metallomics profiling-based nail biomarkers for cancer diagnosis and prognosis
Inventor: KIM JONG SUNG
IPC: G01N33/48
Filed: 2018-06-06
Abstract: The invention provides a non-invasive arsenic speciation and metallomics-based nail biomarkers of chronic disease outcomes including cancers associated with arsenic and toxic metal exposures and the methods for cancer diagnosis and prognosis using these biomarkers. The biomarkers are proportions and ratios of several arsenic species and other metal profiles measured in biological nail samples. Metallomics is the comprehensive analysis of the entirety of metal species within a biological specimen. Our invention has demonstrated for the first time that the proportions of arsenic species in human nails are associated with chronic disease including cancers and differ between individuals with and without chronic disease including cancers. Thus, analysis of arsenic species combined with other interacting metals (such as selenium) in biological nail samples can be used to monitor an individual's exposures related to health and chronic disease outcomes, and to quantify an individual's cancer risk, diagnosis and prognosis. Chronic exposure to toxic metals including arsenic has been linked to a number of human diseases affecting multiple organ systems, including several cancers, diabetes, and cardiovascular and neurological disease. Most cases assessing cancer outcomes associated with arsenic exposure have used on analysis of urine, in which arsenic has a short residence time (3 - 4 days), and which is thus better suited for assessing short-term, acute exposure. Since many arsenic-related cancers arise from chronic exposure and can develop over the course of several years, measuring longer-term biomarkers may prove to be a more relevant assessment. To the best of our knowledge, this is the first invention for indicating exposures related to chronic disease outcomes, disease risk, disease presence, and disease prognosis, specifically related to chronic disease including skin, lung, bladder, and kidney cancer, and type II diabetes. To the best of our knowledge, this is the first large study investigating the associations between arsenic exposure and various cancers using toenail arsenic speciation analysis, a potentially important, more relevant biomarker for chronic diseases. Toenails have been shown to be more reliable as markers of long-term exposure than hair or fingernails, as they are less prone to contamination and washout effects from things such as shampoo, nail polish, or regular handling of items

Title: Dual rate vehicle suspension system
Inventor: HOLT LAURENCE J
IPC: B60G11/50
Filed: 2017-01-06
Abstract: A selectively switchable dual rate vehicle suspension system comprising a pushrod actuated inboard spring configuration, conventionally oriented between the unsprung mass and the sprung mass of one corner of the vehicle, comprising a torsion bar spring of a first predetermined rate, K1, and a coil spring of a second predetermined rate, K2, arranged in series so as to provide a total combined spring rate KT. A lockout actuator is arranged in parallel with the coil spring and configured so that in a first mode it allows the coil spring to move freely and in a second mode prevents motion of the coil spring such that when the lockout actuator is in a first, unlocked, mode the overall vehicle suspension spring rate is defined by the series equation 1/ KT = 1/K1 + 1/K2, and when the lockout actuator is in a second, locked, mode the overall vehicle suspension spring rate is substantially higher as defined by KT = K1, thus selectively providing both a low rate, optimal ride comfort setting and a high rate, optimal handling setting.

Title: Livestock force tub with supplemental wall section, auxiliary space and reduced opacity exit-adjacent wall sections
Inventor: LANGRELL STEPHEN A
IPC: A01K1/00
Filed: 2019-05-29
Abstract: A livestock force tub features a perimeter structure delimiting an interior space of said livestock tub, including a main peripheral wall spanning circumferentially around a central upright axis, an exit situated at or proximate a terminal end of the main peripheral wall and a supplemental wall section at an area adjacent the exit on a side thereof opposite the terminal end of the main peripheral wall. The supplemental wall section increases an angular span of the tub around the central axis to create an auxiliary space beyond the exit. This auxiliary space accommodates a possible uncooperative animal during unloading of the force tub while allowing others to still reach the exit. The supplemental wall section and a terminal section of the main peripheral wall have a lesser opacity than more significantly cladded areas of the main peripheral wall, whereby increased light admission and environmental visibility attract livestock toward the exit.
