Abstract: Traffic signal timing plans are derived from vehicle trajectory or probe data. The probe data is collected and archived in a datastore over a sample time on the order of weeks or longer. Probe data is corrected for clock drift, geo-fence filtered to a selected intersection, and then stop line crossings in the intersection are identified and analyzed along with related data to determine the timing plans and schedule for the intersection. In this way, access to government agency timing plans is obviated so as to save time and expense.

Abstract: A hub assembly for a hybrid module having a first and a second connection partner arranged coaxially with one another, the first connection partner has a first bearing portion and the second connection partner has a second bearing portion, and a plurality of connecting elements. The first and the second bearing portion have receiving openings for receiving the connecting elements. The first and the second connection partner are prepositioned with respect to one another via a form-fitting connection such that the receiving openings in the first and the second bearing portion are each oriented in pairs in a positionally correct manner with respect to one another in the circumferential direction about the main axis H.

Abstract: A linear guide device includes at least one linear guide unit which has a guide housing, in which two annularly closed circulating channels are formed in each of which a multitude of roller bearing elements is received. The guide housing has a single-piece housing intermediate element which contributes to the formation of the circulating channels and through which passes at least one lubrication channel which communicates with the circulating channels. The lubrication channel passes through the single-piece housing intermediate element and extends partly also in an integral pipe-stub-like lubrication appendix of the single-piece housing intermediate element, wherein the lubrication appendix includes a lubrication opening which is accessible from outside the guide housing for bringing in lubricant.

Abstract: An instrument for repairing an atrioventricular heart valve, mitral heart valve or tricuspid heart valve includes a first tube having a tube axis defining an axial direction. A leaflet grabbing structure is arranged at a distal part of the first tube and contiguous to the first tube. The leaflet grabbing structure has a main body and a jaw, the jaw being movable relative to the main body. The jaw has a first proximally facing abutment surface and the main body has a second, distally facing abutment surface. The instrument has a needle that is cannulated and forms an inner tube. The needle is releasable from the first tube and movable relative to the main body in axial directions. The leaflet grabbing structure clamps a leaflet of the heart valve between the first and second abutment surfaces, while the jaw allows the needle to extend therethrough.

Abstract: According to the method, either CO2-free air or pure nitrogen N2 is pumped into the cooling circuit selectively depending on system parameters. To this end, the method ensures that the air injection rate is high enough that, under normal conditions, the hydrogen concentration in the tank and in the riser remains below 2% H2. On air injection, the oxygen O2 (>2 ppm) in the cooling water reacts with the copper in the cooling ducts and a layer of copper oxide forms on the inner walls of said ducts. No reaction is triggered by the injection of nitrogen N2. The CO2 content in the injection air and, at the same time, also the H2 content in the exhaust air are continuously measured and monitored, and an alarm is triggered if adjustable limit values are exceeded. The equipment for performing the method comprises an electronic control unit (65) with an input field and display as a control box, and a pump and a pipe circuit for drawing air in from the riser.

Abstract: At least three acoustic filters circuits FC are arranged on a single chip CH. At least two of them are electrically connected already on the chip for multiplexing. This reduces space consumption and leads to smaller device size.

Abstract: A surface acoustic wave resonator arrangement comprises a piezoelectric substrate (100) and a surface acoustic wave resonator (110) which includes an interdigital transducer (111,112) disposed on the piezoelectric substrate (100). A trench (13 0) is disposed within the piezoelectric substrate (100) facing the resonator (110). Trench (130) causes reflected waves (143,144) in response to waves (141,142) leaking from the surface acoustic wave resonator. Trench (130) is configured such that the reflected acoustic waves (143,144) achieve phases at the edge (115) of the resonator (110) such that the accumulated phases of all the reflected waves received at edge (115) is zero or substantially zero, thereby avoiding constructive interference of the reflected waves with the acoustic waves resonating in the resonator. Thereby undesired acoustic coupling between resonators or influence of waves reflected at edges of the piezoelectric substrate or dicing lines is reduced.

Abstract: An improved DMS filter with electrode structures between a first port and a second port is provided. Wiring junctions are realized in multilayer crossing with dielectric material in between. There are insulating patches (L2) between crossing conductor layers (L1,L3). Signal wirings may be realized with multiple conductor layers (L1, L3) to reduce wiring resistance and the upper conductor layer (L3) of the signal wiring may partly overlap the insulating patches (L2). The insulating patches (L2) may extend over the acoustic path to achieve temperature compensation.
