Abstract: A protection structure for an optical lens module includes a female die, a male die, and an ejector plate. The male die includes a plurality of cores and second cavities. Locating rings are provided on the cores or in the second cavities to protect the cores from tearing and wearing so as to extend their lifespan.

Abstract: A method is disclosed for integrally forming at least one low voltage device and at least one high voltage device. According to the method, a first gate structure and a second gate structure are formed on a semiconductor substrate, wherein the first and second gate structures are isolated from one another. One or more first double diffused regions are formed adjacent to the first gate structure in the semiconductor substrate. One or more second double diffused regions are formed adjacent to the second gate structure in the semiconductor substrate. One or more first source/drain regions are formed within the first double diffused regions. One or more second source/drain regions are formed within the second double diffused regions. The first double diffused regions function as one or more lightly doped source/drain regions for the low voltage device.

Abstract: An automated forced-choice dynamic-dilution olfactometer has an odor evaluation module having two or more panelist stations, with a plurality of sniffing ports at each station. At least one signal element at each station is connected to a data control unit. Separate air lines are connected to one each of the sniffing ports at each station. One of the air lines has an odor introduction port.
