Abstract: A motorization apparatus for a motorized wheel comprises an axle secured to a frame of a vehicle. A rotor unit has poles of magnet material. A stator unit having slots and teeth secured to the axle is inward of said rotor to define a clearance gap therewith such that the rotor unit is rotatable about the stator core. An arrangement of coils is wound around the teeth of the stator unit, the coils adapted to be powered to induce a rotation of the rotor unit relative to the stator unit. A structure comprises hub portions rotatably mounted to the axle, the structure having lateral walls defining an inner volume for the rotor unit and the stator unit, the structure supporting the rotor unit. The structure comprises attachment members connected to spokes of the motorized wheel, located radially inward of the clearance gap between the rotor unit and the stator unit.

Abstract: A guest digital device joins a playback session hosted by a host digital device and synchronizes playback of digital media content with playback on the host digital device. This enables multiple users to listen to or view media at the same time on their respective devices. A time-based synchronization process may be used to initially synchronize playback of the guest digital device to the host digital device. If synchronization is lost, the device may record and analyze audio during playback and a fingerprint-based synchronization approach may be applied that detects a time offset between fingerprints in the analyzed audio. If synchronization is still not achieved, a watermark-based synchronization approach may be applied in which watermarks are actively injected into the audio and the time offsets between the watermarks is detected.

Abstract: A direct-drive brushless DC motorization apparatus is provided. The apparatus includes an outer rotor having poles constructed with segments of forty or forty-four permanent magnets alternatively magnetized north and south. The outer rotor is adapted to be part of a wheel and is rotatable with respect to an axis of the wheel. The outer rotor is mounted about a stator core of ferromagnetic material and is separated from the stator core by a clearance gap. The stator core has forty-two slots, and adjacent slots are separated by teeth. A three-phase winding with coils of insulated wire is wound around the teeth of the stator core. The three-phase winding is divided in two sets of consecutive teeth for each of the three phases, with each of the two sets of a same phase being diametrically opposed in the stator core.

Abstract: Playback of an audio stream is synchronized on multiple connected digital devices by using synchronization fingerprints. Playback actions may furthermore be synchronized on all devices, such as skips and pauses. Furthermore, synchronization may be maintained even in the presence of variations in decoding speed, playback interruptions, and network disconnections. Synchronized playback of streamed audio content on multiple devices is achieved by devices compensating for time drifting induced by network instability and variable playback speed across master and guest devices to reduce the formation of echoes during playback.

Abstract: Embodiments of the invention provide a renderer-agnostic method for representing materials independently from an underlying rendering engine. Advantageously, materials libraries may be extended with new materials for rendering with an existing rendering engine and implementation. Also, new rendering engines and implementations may be added for existing materials. Thus, at run-time, rather than limiting the rendering to being performed on a pre-determined rendering engine, the rendering application may efficiently and conveniently manage rendering a graphics scene on a plurality of rendering engines or implementations.

Abstract: A method for projecting a data set from a first object to a second object includes the steps of defining one or more sub-objects, wherein each sub-object represents a portion of the second object, associating the first object with a first sub-object, expanding a projection cage to substantially encompass both the first sub-object and the first object, and transferring the data set from the first object to the first sub-object using the projection cage. The disclosed method advantageously allows the first sub-object to be defined in a way that avoids undesirable cage intersections, thereby enabling the data set from the first object to be transferred without tedious manual manipulations of the projection cage.

Abstract: A method and system is disclosed for determining a property of an object by measuring ultrasonic attenuation. With the proposed method, a measured ultrasonic interaction signal of the object is compared with a reference signal produced using the same generation and detection setup, but using a reference part. The reference ultrasonic signal has low attenuation, and exhibits equivalent diffraction properties as the object, with respect to a broadband ultrasonic pulse. The difference is attributable to the attenuation of the object. The attenuation as a function of frequency, the attenuation spectrum, is fitted to a model to obtain a parameter useful for identifying one of the many properties of an object that varies with ultrasonic attenuation.

Abstract: A method is disclosed for evaluating the physical properties of a sample, for example, the grain size in a polycrystalline material. An ultrasound field is generated in a local region of the sample with a non-contact source, such as a pulsed laser, such that the generated ultrasound diffuses away from said local region. After waiting until the generated ultrasound field has reached a diffusion regime, the resulting ultrasound field is measured with a non-contact detector. Parameters are adjusted in a mathematical model describing the predicted behaviour of the ultrasound field in the diffusion regime to fit the detected ultrasound field to the mathematical model. In this way, parameters dependent on the physical properties of the sample, such as the diffusion coefficient and absorption coefficient, can be derived. The grain size, for example, can be estimated from these parameters preferably by calibrating the diffusion coefficient to grain size.
