Abstract: A method and apparatus for testing and simulating an access control policy are disclosed. Evaluating an access control policy may be performed by utilizing a deny statement that causes the access request to be rejected despite actions indicated in the access request being authorized. Further, an independent simulation environment may be utilized for testing access control policy evaluation.

Abstract: Systems and methods for scoring investment data using machine learning-based model training. The method includes receiving historical data over a time period. The method further includes determining positive investment data and negative investment data based on the historical data and investment preference data. The positive investment data including characteristics associated with positive assets that align with the investment preference data. The negative investment data including characteristics associated with negative assets that misalign with the investment data. The method further includes calculating machine learning model parameters based on the positive and negative investment data. The method also includes calculating a score corresponding to a new asset based on the machine learning model parameters and new investment data. The method further includes determining whether the new investment data aligns with the investment preference data based on the score and a threshold investment score.

Abstract: An optical arrangement for a motor vehicle includes a head up display light field emitter that emits a light field. At least one mirror is positioned to reflect the light field such that the light field is again reflected by a windshield of the vehicle, and such that the light field is visible to a driver of the vehicle as a virtual image. The at least one mirror has a transparent section. A driver monitoring camera is positioned to capture an image of a face of the driver through the transparent section of the at least one mirror.

Abstract: A package shipping arrangement includes a computer system having a processing block receiving a first digital representation, captured by a camera, of a hand drawn mark on a package to be shipped. The processing block receives a desired destination address of the package, and compares the first digital representation of the mark to other digital representations of marks stored in memory. The processing block determines whether the first digital representation of the mark is different from all the other digital representations of marks. In response to determining that the first digital representation of the mark is different from all the other digital representations of marks, the processing block stores the first digital representation of the mark in the memory block in association with the desired destination address of the package.

Abstract: A motor vehicle includes a driver sensor detecting a position of a human driver of the motor vehicle. A rear view camera captures images of an environment behind the motor vehicle. A display screen is disposed within a passenger compartment of the motor vehicle. An electronic processor is communicatively coupled to each of the driver sensor, the rear view camera, and the display screen. The electronic processor receives images captured by the rear view camera, receives outputs of the driver sensor, determines a position of the driver's head or eyes dependent upon the outputs of the driver sensor, and transmits video signals to the display screen. The video signals are dependent upon the determined position of the driver's head or eyes and dependent upon images captured by the rear view camera.

Abstract: A method of processing signals from an accelerometer/gyroscopic-based input device includes providing the input device within a vehicle. An accelerometer/gyroscopic-based second device is also provided within the vehicle. The input device is manually actuated while the vehicle is in motion. First signals are transmitted from the input device in response to the manually actuating step. Second signals are transmitted from the second device in response to the motion of the vehicle. The first signals are adjusted dependent upon the second signals.

Abstract: A peristaltic pump head includes a housing assembly adapted for mounting to a drive mechanism, a roller assembly arranged with the housing assembly and a flexible conduit extending through the housing assembly and engageable by the roller assembly to impel fluid therethrough. The roller assembly and the flexible conduit are removable from the housing assembly without disconnecting the entire housing assembly from the drive mechanism. The roller assembly can include an axially extending drive shaft, a roller control body fixedly mounted to the drive shaft, at least a first end plate rotatably mounted about the drive shaft, and at least a first roller arm pivotably mounted to the first end plate. The flexible conduit can include a length of hollow tubing made of an elastomeric material, and at least one overmolded end fitting made of a rigid polymeric material and fused to an end of the hollow tubing.

Abstract: Described are techniques for controlling the transfer of heat on various portions of a device or other structure. A structure may include a substrate having a first thermal conductivity. A material having a different thermal conductivity is distributed on the substrate. The position, quantity, and thickness of the material affects the manner in which heat is transferred away from at least one hot spot on the substrate.

Abstract: In some cases, a handheld electronic device may operate in a voice input mode or a scanner input mode. When operating in the voice input mode, the handheld electronic device may record and store audio data in memory. In some cases, the stored audio data may be communicated from the handheld electronic device (e.g., via a Wi-Fi connection) to one or more remote computing devices (e.g., for speech processing). When operating in the scanner input mode, the handheld electronic device may record and store item identifier information (e.g., as barcode data) in the memory. In some cases, the stored item identifier data may be communicated to the one or more remote computing devices (e.g., for item identification processing).

Abstract: A sterilization and humidification apparatus includes a heating chamber, a filter and a humidification chamber. The heating chamber heats a gas so as to sterilize the gas. The humidification chamber is adapted so that a liquid, which has been filtered by the filter, evaporates into the sterilized gas, thereby causing the sterilized gas to cool, and outputting a humidified gas at a desired temperature. The apparatus may include a bypass chamber to provide a path for the gas to bypass the humidification chamber. The apparatus may be adapted particularly for use in an incubator.

Abstract: This disclosure relates generally to directional couplers. In one embodiment, a directional coupler includes a first port, a second port, a third port, a first inductive element, a second inductive element, a first switchable path, and a second switchable path. The first inductive element is coupled between the first port and the second port, while the second inductive element is mutually coupled to the first inductive element. The first switchable path is configured to be opened and closed, wherein the first switchable path is coupled between a first location of the second inductive element and the third port. The second switchable path is configured to be opened and closed, wherein the second switchable path is coupled between a second location of the second inductive element and the third port. In this manner, a directivity of the directional coupler can be switched between a forward direction and a reverse direction.
