  • Publication number: 20240123903
    Abstract: A vehicular dual-state interior rearview mirror assembly includes a mirror head that accommodates an electrochromic mirror reflective element. A video display device is disposed behind a viewable reflective region of the mirror reflective element. With the mirror assembly operating in a first state, the video display device does not display video images at the display screen and the driver of the vehicle views rearward via reflection at the viewable reflective region. With the mirror assembly operating in a second state, the video display device displays video images at the display screen for viewing by the driver. A touch sensor is disposed at an overhang region of the reflective element behind the front substrate and below the video display device. The video display device is operated responsive at least in part to a touch event at the first surface of the front substrate of the electrochromic mirror reflective element.

  • Publication number: 20240092267
    Abstract: A vehicular interior rearview mirror assembly includes a mirror head pivotally adjustable about a mirror support. The mirror head includes a video display device disposed rearward of a prismatic mirror reflective element having a transflective mirror reflector. A touch sensor is disposed at the prismatic mirror reflective element and is associated with circuitry at a flexible printed circuit of the video display device. The video display device is operable to display video images captured by a rearward viewing camera of the vehicle. Light emitted by the video display device passes through the transflective mirror reflector for viewing of displayed video images by the driver of the vehicle viewing the prismatic mirror reflective element. The reflective region of the transflective mirror reflector of the prismatic mirror reflective element reflects at least 40 percent of visible light incident at the front side of the prismatic mirror reflective element.

  • Patent number: 11591309
    Abstract: A method for manufacturing an insecticidal compound and insecticidal compositions comprising the insecticidal compound and methods of use are presented herein. The manufacturing method presented herein allows for a high purity grade of thiocyclam hydrochloride to be synthesized. The insecticidal compositions comprising the thiocyclam hydrochloride can be used for prevention of crop destruction by insects. The use of thiocyclam hydrochloride in insecticidal compositions as described herein can achieve greater efficacy than previously known insecticides, by eliminating the insect pests more reliably and efficiently.

  • Publication number: 20200352167
    Abstract: A flucarbazone sodium hemihydrate method and composition. A method of suppressing growth of grass and broadleaf weeds is described including applying to said weeds at least one dust-free composition comprising flucarbazone sodium-hemihydrate as an active ingredient. A method for preparing flucarbazone sodium-hemihydrate is also described including treating 4,5-dihydro-3-methoxy-4-methyl-5-oxo-N-[[2-(trifluoromethoxy)phenyl]sulfonyl]-1H-1,2,4-triazole-1-carboxamide (MSU) with aqueous sodium hydroxide under pH-controlled conditions; and confirming that a hemihydrate flucarbazone sodium has been obtained.
