  • Publication number: 20210231555
    Abstract: Disclosed embodiments may relate generally to a micro airflow generator which does not use fan(s) or a heater to generate airflow (for example in a compact optical PM sensor). Rather, disclosed embodiments typically may use induced movement of a membrane/diaphragm element to generate air flow (wherein movement of the membrane in turn induces movement in air). For example, a membrane or diaphragm element could be driven by an (electronic) actuator element, such as an electro-magnetic actuator or piezo disc bender (or some other means of vibrating/moving the membrane element in a way which induced airflow). In some embodiments, the electro-magnetic actuator itself may include a membrane (such that the electro-magnetic actuator might encompass the membrane and the electronic actuator element, such as a magnet and corresponding coil) and/or the piezo disc bender might serve as both the membrane/diaphragm and the electronic actuator element.

  • Patent number: 11056400
    Abstract: Nanowire devices and fin devices are formed in a first region and a second region of a substrate. To form the devices, alternating layers of a first material and a second material are formed, inner spacers are formed adjacent to the layers of the first material, and then the layers of the first material are removed to form nanowires without removing the layers of the first material within the second region. Gate structures of gate dielectrics and gate electrodes are formed within the first region and the second region in order to form the nanowire devices in the first region and the fin devices in the second region.

  • Patent number: 11036944
    Abstract: Embodiments of the present disclosure provide an alternative illuminator assembly and corresponding imaging assemblies utilizing the alternative illuminator assembly. The alternative illuminator assembly may provide alternative illuminations from those produced by an imager engine, such that the alternative illuminations may provide specific illuminations at specific illumination angles to illuminate a field of view for a desired purpose. In an example context, the alternative illuminator assembly provides one or more alternative illuminations for improving the likelihood of successfully reading specific direct part marking indicias of various types. Embodiments are provided using overlapping subassemblies that enable a small form factor assembly that can fit into mobile apparatus chasses, for example within conventional cell phone housings of around 7 millimeters.

The first transistor and the fourth transistor are controlled by a light-emitting signal. The third transistor and the fifth transistor are controlled by a scan signal. The light-emitting device, the first transistor, the second transistor, the fourth transistor, and the fifth transistor are serially connected between a system high voltage and a system low voltage. The third transistor is coupled between a data signal and a control terminal of the first transistor. The first capacitor is coupled between a control terminal and a downstream terminal of the second transistor. The fifth transistor is coupled between the downstream terminal of the second transistor and a charging reference voltage. A current of the charging reference voltage is less than a current of the system low voltage.

  • Publication number: 20210104068
    Abstract: A controller for executing a task based on probabilistic image-based landmark localization, uses a neural network, which is trained to process images of objects of a type having a structured set of landmarks to produce a parametric probability distribution defined by values of parameters for a location of each landmark in each processed image. The controller submits the set of input images to the neural network to produce the values of the parameters that define the parametric probability distribution over the location of each landmark in the structured set of landmarks of each input image. Further, the controller determines, for each input image, a global landmark uncertainty for the image based on the parametric probability distributions of landmarks in the input image and executes the task based on the parametric probability distributions of landmarks in each input image and the global landmark uncertainty of each input image.
