Abstract: Creating scent models and using scent models in cross-reality environments can include capturing experience data identifying a scent detected and a context in which the scent was detected. The experience data can be provided to a scent modeling service to generate a scent model that can represent perceived scents and perceived scent intensities for a user. The scent model can be used to generate cross-reality session data to be used in a cross-reality session presented by a cross-reality device. The cross-reality device can include a scent generator and can generate the cross-reality session using data obtained from the user device. The cross-reality device can generate a further scent during the cross-reality session based on the scent model.

Abstract: A high-brightness liquid crystal display device includes a display module; a temperature controller abutting a back surface of the display module, a first ventilation channel being formed in the temperature controller; and fans disposed on the display module in correspondence to the first ventilation channel of the temperature controller. The fans form an airflow that flows through the first ventilation channel, to adjust the temperature of the display module. According to the present invention, the temperature controller abuts the back surface of the display module to implement temperature control on the back surface of the display module. The back surface of the display module is a lamp panel, and the temperature controller abuts the lamp panel. The airflow formed by the fans quickly reduces and increases the temperature of the lamp panel, thereby ensuring that the lamp panel works at an appropriate environmental temperature.

Abstract: A bi-static integrated pulse radar in the millimeter wave band based on a digitally modulated transmitter and an analog processing receiver. The front-end correlator uses a sampler to compress the sensing data, enabling a low-speed and energy efficient digital backend while delivering a high range resolution. The radar may be implemented as a system on chip (SoC) with a total power consumption of a few hundred milliwatts (mW), a surface area of less than four mm2 with less than ten percent of the total power corresponding to the analog baseband and digital back-end. The system performance indicates the measured distance from the correlator output has an RMS error of about ten centimeters (cm) and the integral non-linearity is less than ten cm across the entire target range, demonstrating the superior range resolution with superior energy efficiency.

Abstract: The techniques and systems described herein relate to manufacturing, characterizing, and/or identifying one or more types of magnetic nanowires (MNWs). One or more types of MNWs may be associated with different objects, and a system may identify the objects based on the magnetic nanowires associated with the objects. For example, such techniques may involve characterizing the types of MNWs based on magnetic field transmission characteristics and ferromagnetic resonance characteristics of each type of MNW. In some examples, the techniques described herein may enable the identification of each of a plurality of types of MNWs present in a sample or object based on a combined transmission value of the sample. Such techniques may enable the development and use of barcode-like systems of different types of MNWs for labeling and identifying objects of interest.

A cloud service system accesses a temporary container containing a manifest and a plurality of web parts for the web application. The manifest includes a list of contents of the temporary container and defines an appearance and functionality of the web application.

The cloud service system configures each web part and the user interface environment to interact as defined by the manifest. The user interface environment reconstructed on the cloud service replicates the appearance and functionality of the web application operating system in the source environment.
