  • Patent number: 11183256
    Abstract: According to a certain embodiment, the semiconductor memory device includes a memory cell array, a control circuit, and a data register storing an erase verify fail flag. An erase target block is divided into word line groups. The control circuit includes: a counter configured to count the number of the erase verify fail flags to be output as a count value for each group; a plurality of counter registers configured to store the count value for each group; an arithmetic circuit configured to take a difference of the plurality of count values respectively stored in the plurality of counter registers and to output a result of the difference as a number of second fail flags; and a comparator configured to compare the number of criteria of the erase verify fail flag and the number of the second fail flags to be output as a memory state detected result.

  • Publication number: 20210349295
    Abstract: A folded optical system that comprises two prisms with refractive power and in which at least one surface of at least one of the prisms is not rotationally symmetric. The materials and surfaces of the prisms in the folded optical system may be selected to provide a low F-number (e.g., <=2.4), full field of view (FOV) of 30 degrees or less. The folded optical system may be implemented in a small package size while still capturing sharp, high-resolution images, making embodiments of a camera including the folded optical system suitable for use in small and/or mobile multipurpose devices.

  • Patent number: 11163096
    Abstract: Compact lens systems that may be used in small form factor cameras. The lens system may include a master lens with two or more lens elements arranged along an optical axis and having refractive power, and an optical actuator located on the object side of the master lens that may provide autofocus (AF) and/or optical image stabilization (OIS) functionality for the camera. An aperture stop for the camera may be included in the optical actuator, for example between a substrate and a flexible optical element of the optical actuator. Including the aperture stop in the optical actuator rather than in the lens stack may allow the optical actuator to be smaller in the X-Y dimensions (perpendicular to the optical (Z) axis) than it would be in a similar camera with the aperture stop located in the lens stack.

  • Patent number: 11163141
    Abstract: Compact folded lens systems are described that may be used in small form factor cameras. Lens systems are described that may include three lens elements with refractive power, with a light folding element such as a prism, located between a first lens element on the object side of the lens system and a second lens element, that redirects the light refracted from the first lens element from a first axis onto a second axis on which the other lens elements and a photosensor are arranged. The lens systems may include an aperture stop located behind the front vertex of the lens system, for example at the first lens element, and an optional infrared filter, for example located between the last lens element and a photosensor.

  • Publication number: 20210323092
    Abstract: An additive manufacturing apparatus includes: a material supply unit that supplies a build material to a process area of an additive target surface; an irradiation unit that irradiates the process area with a laser beam that melts the build material; and a control device that controls the material supply unit and the irradiation unit for creating at least a part of an object using a dot-shaped bead, the dot-shaped bead being formed of the build material melted by radiation of the laser beam. The additive manufacturing apparatus can improve the shape accuracy of the object.

  • Publication number: 20210294074
    Abstract: A folded lens system that includes lenses with refractive power and two light folding elements such as prisms. A first lens on a first axis refracts light to a first folding element. The first folding element redirects the light from the first axis onto a second axis on which one or more lenses are arranged. The lenses on the second axis refract the light to a second folding element. The second folding element redirects the light onto a third axis on which a sensor is disposed. The lens system may include a front aperture. The sensor may be moved on the third axis to provide autofocusing, or alternatively the lens system may include one or more optical actuators that provide autofocusing. The lens system may have a low F-number (<=2.8), and may have a 35 mm equivalent focal length in the medium to long telephoto range.

  • Publication number: 20210191133
    Abstract: Recording indicators for devices with cameras that provide protection from tampering so that the recording indicators cannot be easily disabled or masked. Recording indicators that are external to the camera lens and that emit visible light in an encrypted pattern are described. The device may process captured frames to detect the encrypted pattern; if the encrypted pattern cannot be detected, recording is disabled. In addition, modular accessories are described that the user has to attach to the device to enable recording; the presence of the modular attachment indicates to persons in the environment that they may be being recorded.

  • Patent number: 10877556
    Abstract: An eye tracking system for detecting position and movements of a user's eyes in a head-mounted display (HMD). The eye tracking system may include at least one near-IR (NIR) eye tracking camera positioned at each side of the user's face and pointed towards eye-facing surfaces of eyepieces of the HMD, an illumination source that emits NIR light towards the user's eyes, and hot mirrors located between the eye-facing surfaces of the eyepieces and the user's eyes. The hot mirrors reflect at least a portion of NIR light, while allowing visible light to pass. The cameras capture images of the user's eyes reflected by the hot mirrors. Positioning the hot mirrors at or near the eye-facing surfaces of the eyepieces allows the cameras to be placed at the sides of the user's face without having to image through the eyepieces.

  • Publication number: 20200183058
    Abstract: Light-absorbing flange lenses that may be used in the lens stacks of compact lens systems. In a light-absorbing flange lens, the effective area of the lens is composed of a transparent optical material, and at least a portion of the flange of the lens is composed of an optical material that absorbs at least a portion of the light that enters the flange. Using light-absorbing flange lenses may allow the lens barrel to be eliminated from the lens system, thus reducing the X-Y dimensions of the lens system when compared to conventional compact lens systems that include a lens stack enclosed in a lens barrel. In addition, using a light-absorbing material in the flanges of the light-absorbing flange lenses may reduce or eliminate optical aberrations such as lens flare, haze, and ghosting in images.

  • Patent number: 10564401
    Abstract: Compact narrow angle lens systems that may be used in small form factor cameras. The lens system may include six lens elements with refractive power, and may provide lower F-numbers while maintaining or improving imaging quality and package size when compared to other compact lens systems. Total track length of the lens system may be 6.5 millimeters or less, for example 5.9 or 6 millimeters. Focal length of the lens system may be 7.0 millimeters or less, for example 6.6 millimeters. The lens system may include an aperture stop located behind the front vertex of the lens system, for example between the first and second lens elements, that effectively moves the ideal principal point of the camera to in front of the front vertex. The lens system may provide a focal ratio of 2.8 or less, for example 2.6 or 2.4.
