Abstract: Embodiments of a semiconductor memory device include a substrate having a first region with peripheral devices, a second region with one or more memory arrays, and a third region between the first and the second regions. The semiconductor memory device also includes a protective structure for peripheral devices. The protective structure for peripheral devices of the semiconductor memory device includes a first dielectric layer and a barrier layer disposed on the first dielectric layer. The protective structure for peripheral devices of the semiconductor memory device further includes a dielectric spacer formed on a sidewall of the barrier layer and a sidewall of the first dielectric layer, wherein the protective structure is disposed over the first region and at least a portion of the third region.

Abstract: A technique for improving wireless communication characteristics involving matching transmitter antenna patterns to receiver antenna patterns. In a specific implementation, the transmitter antenna pattern adapts to changing parameters, such as when a smartphone is initially held in a first orientation and is later held in a second orientation. Because the transmitter antenna pattern matches receiver antenna patterns, signal quality between stations improves. In some implementations, antennas are organized and mounted to maximize spatial diversity to cause peak gains in different directions.

Abstract: Disclosed herein is a novel, compact optical particle identification and characterization system and method of use within both gaseous and liquid media. The system can implement both elastic and inelastic light scattering techniques simultaneously under the same sensor platform. By separating the sensing components from the electro-optical unit and using optical fibers for interconnection, only the sensing components need to be exposed to the environmental conditions. This reduces the design constraints on the electro-optical unit and permits the incorporation of optical components into the sensing probe that can withstand high-temperature, high-pressure, and corrosive environments. Thus, the system can be used in benign, moderate, and harsh environments.

Abstract: A plastic bag comprising two panels and a flap joined to one of the panels and configured for folding over the other of the panels for closure of the bag, wherein at least a portion of the flap has a tackiness which is greater than the tackiness of its associated panel. A stack of bags having a flap with greater tackiness than the tackiness of the major panels of the bags.

Abstract: An optical imaging lens may include a first, a second, a third, and a fourth lens elements positioned in an order from an object side to an image side along an optical axis. Through designing concave and/or convex surfaces of the four lens elements, the optical imaging lens may provide improved imaging quality and optical characteristics, and have the ability to cooperate the demand of present smaller-sized electronic product while the optical imaging lens may satisfy TTL/TL?1.700 and EFL/ImgH?2.500, wherein a distance from the object-side surface of the first lens element to an image plane along the optical axis is represented by TTL, a distance from the object-side surface of the first lens element to the image-side surface of the fourth lens element along the optical axis is represented by TL, an effective focal length of the optical imaging lens is represented by EFL, and an image height of the optical imaging lens is represented by ImgH.

Abstract: Disclosed herein is a novel system and method for the remote characterization of visible emissions, and more particularly, to compact, optical sensors which can remotely measure the opacity of a visible emission plume from a stationary source. Assessing visible emissions is important for compliance with environmental regulations and to support the regulatory reporting needs of Federal and State inspectors. By reducing the power consumption of the laser source and the signal processing, a compact, handheld or hand portable, battery-operable opacity measurement system can be realized while allowing eye-safe operation. The system and method may also be applied to non-stationary sources.

Abstract: A swingable exercise bike includes a base having with a pivot portion for pivoting a bike body to swing left and right relative to the base. Left and right sides of the pivot portion are provided with cushion devices, respectively. The cushion devices are connected to the bike body and provide a horizontal cushioning resistance when the bike body swings left and right, thereby ensuring stable support of the bike body and improving safety in use.

Abstract: A swingable exercise bike includes a base having a first pivot portion for a bike body to be pivotally connected to the first pivot portion so that the bike body can swing left and right relative to the base. Left and right sides of the first pivot portion are provided with first connecting rods. The first connecting rods each have one end pivoted to the base and another end extending in a height direction and pivoted to a second connecting rod. The second connecting rod is further pivoted to the bike body. When the bike body swings left and right, the first and second connecting rods are pivoted. The two second connecting rods are connected with a cushion device disposed in a horizontal direction, which can generate a damping effect when the two second connecting rods are pivoted by the bike body, thereby cushioning the swing of the bike body.

Abstract: A package for storing perishable goods. Film forming the package has an inner layer that defines an interior surface of the package and is formed from a polyethylene and a tack agent that has migrated to the interior surface to provide tackiness. The tackiness permits cold resealing of the package after it has been opened, without substantially adhering to the perishable goods so that the perishable goods can be non-destructively removed from the package. An outer layer of the film defines an exterior surface of the package and is formed from another polyethylene. The polyethylene of the outer layer is configured to block migration of the tack agent through the outer layer such that the exterior surface is substantially non-tacky.

Abstract: Wireless electronic devices include one or more wireless antennas to provide for wireless communications. The antenna cables are routed internally within the device and typically noise from components located on a circuit board may couple to the antenna cables and cause a degradation in wireless performance, impact antenna sensitivity and cause packet loss. Utilizing raised pathways in a heat sink utilized for thermal transfer of heat to a housing enables tunnels to be formed between the housing and the heat sink. Routing the antenna cables through the tunnels improves noise isolation for the antenna cables while still maintaining the heat transfer. The raised pathways are configured to not interfere with components on the circuit board or components included in the housing. The wireless antennas may be mounted within the housing instead of on the board so no portion of the antenna cables are located on the circuit board.
