  • Publication number: 20180255252
    Abstract: An optical system and method may relate to capturing extended dynamic range images. In an example embodiment, the optical system may include a lens element configured to receive incident light and a beam splitter optically coupled to the lens element. The beam splitter is configured to separate the incident light into at least a first portion having a first photon flux and a second portion having a second photon flux. The first photon flux is at least an order of magnitude greater than the second photon flux. A controller may be configured to cause a first image sensor to capture a first image of the first portion of the incident light according to first exposure parameters and cause a second image sensor to capture a second image of the second portion of the incident light according to second exposure parameters.

  • Publication number: 20180136321
    Abstract: Described herein are methods and systems for protecting a light detection and ranging (LIDAR) device against external light that is originated at a light source other than a light source of the LIDAR device and that is being emitted towards the LIDAR device. In particular, the LIDAR device may be equipped with a mitigation system that includes an interference filter, an absorptive filter, an adaptive filter, and/or a spatial filter. Additionally or alternatively, the LIDAR device may be operated to carry out reactive and/or proactive mitigation operations. For example, the LIDAR device may be operated to vary over time characteristics with which light is being emitted and to only detect light having characteristics that match the characteristics with which light is being emitted. In another example, the LIDAR device may be operated to activate a shutter to block the external light from being detected by the LIDAR device.

  • Patent number: 9300941
    Abstract: An input stereoscopic video signal has a first frame sequence (SL) in a left-eye channel and a second frame sequence (SR) in a right-eye channel, the second frame sequence (SR) having a zero or non-zero time offset ?1 with respect to the first frame sequence (SL). It is converted into an output stereoscopic video signal having a third frame sequence (S?L) in the left-eye channel and a fourth frame sequence (S?R) in the right-eye channel. The fourth frame sequence (S?R) has a zero or non-zero time offset ?2 with respect to the third left-eye frame sequence (S?L). The two time offsets ?1, ?2 may be different ?2??1), in which case the conversion comprises a time interpolation of the frames of at least one of the first and second frame sequences with interpolation parameters selected to apply a relative time shift of ?2??1 to the right-eye channel with respect to the left-eye channel.

  • Publication number: 20160029024
    Abstract: For compressing a video signal, a local multiscale transform is applied to a frame of the video signal to obtain coefficient blocks. The coefficients of each block are distributed into coefficient groups associated with that block. A plurality of the coefficient groups associated with a block are processed. The processing of one of the groups comprises determining an exponent for encoding the coefficients of that group. Mantissas are determined for quantizing the coefficients of the plurality of groups in combination with the exponents respectively determined for these groups. Coding data including each exponent determined for a coefficient group and the mantissas quantizing the coefficients of the group in combination with this exponent are stored in an external frame buffer. The mantissas determined for quantizing the coefficients of one of the groups are represented in the coding data by a respective number of bits depending on the exponents determined for the plurality of coefficient groups.

  • Patent number: 8784558
    Abstract: Portland Cement-based concretes and mortars exhibit significant reduction in shrinkage cracking when combined with Magnesium Oxide (MgO), Shrinkage Reduction Admixtures (SRA) and Super Absorbent Polymers (SAP). However, MgO is a solid that reacts with water, SRA is a liquid, and SAP if not added properly could pull water out of the system and thus increase shrinkage. Unique admixture blends used as supplementary cementing materials that do not significantly affect concrete or cement strength properties of Portland cement itself address such issues. Proper ratios of MgO, SRA and/or SAP perform better against crack reduction when compared to commonly used Expansive Cements (EC).

  • Patent number: 8603237
    Abstract: Despite the excellent properties associated with Magnesium OxyChloride (Sorel) based cements and Magnesium OxySulfate based cements, water and corrosion resistance has been limiting factors for achieving greater commercial applications. Such issues can be addressed by incorporating various alkali metal phosphates, such as Magnesium mono- or dihydrogen phosphate (MgHPO4 or MgH2PO4) with alkali metal fatty acids; such as Magnesium Stearate; and metal or alkali metal sulfates such as Aluminum Sulfate or Magnesium Sulfate. Water resistance is further enhanced by either pre-carbonating the mix water or the liquid magnesium chloride phase of the cements, or by adding a carbonate into the powder phase. Accelerated cure of this system has also been obtained by using various inorganic metal oxides. Additionally, improved corrosion resistance is achieved through the use of certain phosphates, zeolites, nitrites and other novel additives.

  • Publication number: 20130115835
    Abstract: A high performance, light weight construction board includes unique low solids Magnesium Oxychloride binder systems filled, Expanded Polymer Beads (EPB) blended with Expanded Perlite and/or with Coal Fuel Fly Ash. Weight reductions for such compositions by incorporating proteinaceous foaming agents into the binder matrix. The use of Calcium and other alkali earth chlorides mixed with magnesium chloride, or totally replacing magnesium chloride, provides unexpected improvements in binder strength. The use of a unique polymer scrim with felt construction provides improved compressive and directional strength properties while also providing superior board pull and shear properties.

  • Publication number: 20130068695
    Abstract: A blend of micro-crystals of magnesium ammonium phosphate and other seed materials with magnesium hydroxide slurries reduces struvite scale in wastewater collection systems leading into waste-water treatment plants. These “seeds” act as attractants to phosphates and ammonia to allow the seeds to grow and remain dispersed throughout the waste water system. This greatly minimizes, or prevents struvite scale from building up in unwanted areas such as pipes, pumps, and valves that could potentially cause water flow blockage.

  • Patent number: 8308148
    Abstract: A plug-in hydraulic body to frame mounting assembly is mounted to a conventional elastomeric body mount device to increase the control of vibration from the operation of the automotive frame to the automotive component supported thereon. The connecting member of the hydraulic mounting assembly threads onto the end of the fastener passing through the conventional elastomeric body mount device and anchors the outer can to a bridging can connected to the underside of the frame offrigger bracket to provide a true plug-n-go vibration control enhancement that can be added to any desired body mount location. The deflection of the fastener during operation of the elastomeric body mount device drives the operation of the hydraulic mounting assembly to dampen the deflection of the fastener in the elastomeric body mount corresponding to the transfer of operational loads between the body component and the offrigger bracket to which the body component is mounted.
