Abstract: The following generally relates to using Augmented Reality (AR) to enhance pedestrian navigation. In some examples, AR techniques are applied to provide AR indications of a location of a group member that includes two or more AR devices. In these examples, AR techniques may be applied to determine a relative position of the group member and/or provide navigational guidance to the group member. In other examples, AR techniques are applied to provide AR-assisted pedestrian guidance. In these examples, AR techniques may be applied to present an AR display that includes information for a point of interest along a route.

Abstract: Methods for cleaning a die face for an extruder include: positioning an articulating tool adjacent the die face while the die face is installed on the extruder, the die face defining a plurality of die orifices; triggering operation of the articulating tool and thereby articulating an end effector coupled to the articulating tool; and contacting the end effector against one or more surfaces of the die face and thereby removing fouling from the die plate. Methods may include: pausing production of a polymer pellet product from the extruder when at least one of the pressure at the die or a polymer pellet product properties indicates fouling at the die; removing a polymer residue from one or more orifices in the die with an articulating tool equipped with an end effector while the die is mounted on the extruder; and resuming production of the polymer pellet product.

Abstract: A receiver configured to remove a bias of a homodyne detector is provided. The receiver produces at least one clone local oscillator (LO) pulse per LO pulse for the reference pulse and per LO pulse for the data-carrying pulse. Measurement made using clone LO pulses are used to compensate for the bias in reference measurements and data-carrying measurements. Clone LO pulses are produced when the reference pulses and the data-carrying pulses are not expected to be present at the homodyne detector. The bias corrected reference measurements may be used as feedback to maintain a timing synchronization of the LO for the reference pulse and the LO for the data-carrying pulse with the corresponding reference pulse and the data-carrying pulse, respectively and for polarization correction. The receiver may be incorporated into a continuous variable (CV) quantum key distribution (QKD) system.

Abstract: A system and method are provided to yield a QRNG based on homodyne detection of quantum noise (e.g., vacuum noise measured as shot noise) generated from a local oscillator, such as an LED. In one embodiment, a QRNG may be provided that is adjustable based on a control input to produce a random output that can be translated to one or more random data bits.

Abstract: A blender appliances includes a control mechanism to stop the blade from spinning within two seconds without the difficulty and expense of adding a brake. The subject blender detects the load reported from a motor load sensor and compares it to a predetermined threshold load. The motor operates at any of the user selected speeds if the motor is operating above the threshold load and operates at or less than a predefined first speed limit if the motor load is less than the threshold load.

Abstract: A blender for blending foodstuff comprises a base and a blender jar removably mountable to the base. The base encloses a motor and a cooling fan. The cooling fan is selectively operable and positioned to blow or draw air across at least a portion of the motor. The blender jar has one or more selectively rotatable blades. The motor is selectively operable to rotate the blender jar blades. The selective operation of the motor is independent of the selective operation of the fan, such that (1) the fan is operable when the motor is not operating, (2) the motor is operable when the fan is not operating, and (3) the fan and the motor are operable at different respective speeds at a same time.

Abstract: An automated mix in-cup apparatus includes a frame having a cup-holder to secure a tapered cup selectively placed therein, and a first motor operatively connected to the cup-holder to rotate the cup-holder. A reciprocating carriage is axially supported by the frame and supports a second motor and a rotatable mixing blade to mix a consumable material. The mixing blade is secured to a shaft axially extending from the second motor, the shaft defining a longitudinal axis and the second motor configured to rotate the shaft and the mixing blade. Reciprocal movement of the carriage axially translates the mixing blade into and out of the tapered cup in the cup-holder. The cup-holder and the first motor are oriented at an incline, defining a tilt angle relative to the longitudinal axis of the shaft, whereby the shaft and the rotatable blade are positioned off-center relative to the tapered cup in the cup-holder.

Abstract: The present disclosure describes an automated blend in-cup apparatus and the related method of operation. The disclosure relates generally to the field of mixing consumable material. More specifically, the disclosure relates to a mixer that is automatically operable to lower a mixing blade into a cup or vessel that contains material to be blended/mixed. A carriage reciprocates on a frame. A pulley system is also located on the frame and a power cord is routed through the pulley system. A moveable pulley in the pulley system moves in the opposite direction of the reciprocating carriage. The apparatus further comprises a well with an inlet manifold and a drain and a fixed but removable cup-receiving holder. Overall, the apparatus is effective, fast, easy to operate, safe, and clean.

More specifically, the disclosure relates to a mixer that is automatically operable to lower a mixing blade into a cup or vessel that contains material to be blended/mixed. A shield is automatically lowered to at least partially isolate the cup. The apparatus further comprises a well with an inlet manifold and a drain and a fixed but removable cup-receiving holder. The shield can include a magnetic portion that is detected by a first sensor on the apparatus. A safety interlock prevents the actuation of the mixing blade in the event that the magnetic portion is not proximate to the first sensor. Overall, the apparatus is effective, fast, easy to operate, safe, and clean.
