Title: Calculating developer time during development process
Inventor: ROSALIND TOY ALLEN RADCLIFFE
IPC: G06Q10/06
Filed: 2021-07-28
Abstract: It includes computer-implemented methods, computing systems and computer program products for calculating an active time on a software application with respect to a first work item. A computer-implemented method includes retrieving activity data from a software development application and a plurality of input signals generated by a peripheral device. The method further includes determining a causal relationship between the input data and any events described by the activity data. In response to a determination of a causal relationship, a first time interval is calculated between an initial signal and a final signal of the plurality of input signals. The first time interval is compared to an estimated time interval. A schedule of a second work item is determined based on the comparison, wherein the first time interval relates to a first work item.

Title: Motion control of a motion device
Inventor: TIAGO MIGUENS RIJO BRANCO JORGE
IPC: G05D1/02
Filed: 2021-12-21
Abstract: A method for generating a trajectory to control the movement of a motion device such as a load handling device (130, Fig 6) associated with a grid framework storage framework structure (1, Fig 1). The method involves (i) receiving a trajectory specification comprising a commanded position, (ii) receiving at least one jerk constrain and (iii) using the at least one jerk constraint to generate a sequence of one or more trajectory segments. Each trajectory segment is respective portions of the trajectory prescribing a jerk reference, an acceleration reference, a velocity reference and a position reference as a function of time; and each generated based on predicting a value of a parameter using a root finding algorithm to find a root of an objective function. Acceleration and/or deceleration constraints may also be received and an updated command position may comprise a forced deceleration, requiring termination of the trajectory sooner than that of the commanded position. The objective function is an amount of positional deviation of the magnitude of the position reference from the commanded position when the velocity reference and the acceleration reference is substantially zero and the root corresponding to the value of the parameter where the positional deviation from the commanded position being less than a predetermined threshold. Any difference between final velocity and the reference thereof, defines a velocity delta. An associated trajectory generator, load handling device per se and non-transitory computer medium are also disclosed. Flowchart 200 illustrates the stages in adapting motion constraints with instructions received from device 130 to trajectory generator 204, the generation of motion/trajectory profile 206 and the periodical advancement therethrough 208.

Abstract: Cylindrical fibrous structures comprising a fibrous mass of nonwoven, synthetic, polymeric microfibers wherein the microfibers are substantially free of fiber-to-fiber bonding and secured to each other by mechanical entanglement or intertwining, the fiber structure having a substantially constant voids volume over at least a substantial portion of the structure and, preferably, a graded fiber diameter structure, both as measured in the radial direction. The structures are particularly useful as depth filters.The method for preparing such fibrous structures comprises the steps of:(a) extruding synthetic, polymeric material from a fiberizing die and attenuating the extruded polymeric material to form microfibers by the application of one or more gas streams directed toward a rotating mandrel and a forming roll in operative relationship with the mandrel;(b) cooling the synthetic, polymeric microfibers prior to their collection on the mandrel to a temperature below that at which they bond or fuse together, thereby substantially eliminating fiber-to-fiber bonding; and(c) collecting the cooled microfibers on the mandrel as a nonwoven, synthetic fibrous mass while applying a force on the exterior surface of the collected microfibers by the forming roll; wherein the process variables are controlled to form the cylindrical fiber structure with at least the major portion of the fibrous mass having a substantially constant voids volume.

Abstract: An apparatus for cooling a hot product gas, the latter is passed through a tubular zone. The product gas contains particles which, on entering the tubular zone, are tacky, but lose their tackiness through cooling in said zone. Within said zone a cooling gas flow forms a gas wall, which prevents contact between the product gas or the tacky particles contained therein, and one of the fixed walls in the tubular zone. Thus within an outlet connection (2) forming the tubular zone is provided an anular insert (3), which forms a gap (4) with the outlet connection. A cooling gas is blown into this gap counter to the flow direction of the product gas. At the end of the insert, this cooling gas is deflected by the product gas and flows within the insert in the same direction as the product gas and protects the inner wall of the insert from the latter. This product gas is cooled to such an extent by the action of the cooling gas that the particles in the product gas have lost their tackiness at the outlet-side end of the insert.

Abstract: An optical information recording medium comprising a light transmitting substrate, a light absorptive layer overlaying the substrate to absorb a laser beam and a light reflective layer overlaying the light absorptive layer, wherein an optical parameter represented by  rho  = nabsdabs/ lambda  where nabs is the real part of the complex refractive index of the light absorptive layer, dabs is the thickness of the light absorptive layer and  lambda  is the wavelength of a reading laser beam, is 0.05 </=  rho  </= 0.6, and the imaginary part kabs of the complex refractive index of the light absorptive layer is at most 0.3.
