Publication number: 20240175904Abstract: An electric vehicle (EV) charging system is described herein. The EV charging system may be configured to determine if a component in the EV charging system is operating properly based upon current usage. For example, an EV charging station controller may measure a current corresponding to an input to an EV charging station. The EV charging station controller may further measure currents of reference components in the EV charging station, and then use the measured currents to determine if a component in the EV charging station is operating properly. In some examples, the component is a heating, ventilation, and air conditioning (HVAC) component in an EV charging station because it is particularly useful to know the operational status of an HVAC in EV charging systems (e.g., to ensure that the components charging the EV are the correct temperature).Type: ApplicationFiled: November 28, 2022Publication date: May 30, 2024Inventors: Jamshed Nabizada, Hsuan-Chung Lee

Patent number: 11990488Abstract: A grid structure in a pixel array may be at least partially angled or tapered toward a top surface of the grid structure such that the width of the grid structure approaches a near-zero width near the top surface of the grid structure. This permits the spacing between color filter regions in between the grid structure to approach a near-zero spacing near the top surfaces of the color filter regions. The tight spacing of color filter regions provided by the angled or tapered grid structure provides a greater surface area and volume for incident light collection in the color filter regions. Moreover, the width of the grid structure may increase at least partially toward a bottom surface of the grid structure such that the wider dimension of the grid structure near the bottom surface of the grid structure provides optical crosstalk protection for the pixel sensors in the pixel array.Type: GrantFiled: March 12, 2021Date of Patent: May 21, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Wei-Lin Chen, Ching-Chung Su, Chun-Hao Chou, Kuo-Cheng Lee
