    摘要： Magnetic alignment marks are recorded on a recording surface of a magnetic hard disk to mark the location where the disk is abutted against the hub of the spindle of a multiple-disk servo-writer. The alignment marks for each recording surface may be different so as to distinguish between top and bottom disk surfaces so that when the discs are assembled onto the spindle of a disk drive they may be assembled with the proper orientation, i.e., the top surface is mounted “up.” The marks may be large, low frequency patterns that are both written and detected by non contact means other than the servo-track writer's or the disk drive's heads.

    摘要： A low-noise, high-gain optical image amplifier includes a multi-mode pump source that injects optical energy into an active fiber's inner cladding to excite the dopant ions in a 2-D array of doped cores and provide gain. The cores are arranged to sample and collect light from an image incident on one end of the fiber, amplify the light and output an amplified pixilated image at the other end of the fiber. The multi-core active fiber preserves the spatial pattern and spectrum of the incident image. The cores may be configured as single-mode cores to preserve phase information or multi-mode cores to scramble the phase information. It is often desirable for the gain to be approximately uniform across the 2-D array. This can be achieved by pumping uniformly doped cores into their respective saturation regions.

    摘要： Implementations of an air conditioner compressor cover are provided. In some implementations, the air conditioner compressor cover may comprise a first piece of material sized to cover a first portion of a top opening of an air conditioner compressor unit and a second piece of material sized to cover a second portion of the top opening of the air conditioner compressor unit. A portion of a first side of the first piece of material is connected to the air conditioner compressor unit with hinges and a portion of a first side of the second piece of material is connected to the air conditioner compressor with hinges on opposing sides of the air conditioner compressor unit such that when air is not blowing out of the top opening of the air conditioner compressor unit, a second side of the first piece of material and a second side of the second piece of material rest adjacent to each other and when air begins to blow out of the top opening of the air conditioner compressor unit, the first piece of material rotates about its hinges in a first direction and the second piece of material rotates about its hinges in a second direction that is opposite from the first direction.

    摘要： A host device for a wireless network may be configured to implement at least two virtual access points for connecting client devices to the wireless network. A user virtual access point enables a client device to connect to the wireless network and transmit network traffic to other devices connected to the wireless network. In addition, a setup virtual access point provides an additional access point to connect to the wireless network when network credentials for the user virtual access point, such as a service set identifier (SSID) or a password, are changed by a user. When a client device cannot find the user virtual access point based on a stored SSID or password, the client device may be configured to automatically reconnect to the setup virtual access point to request a new SSID and network credentials for the user virtual access point.

    摘要翻译： 用于无线网络的主机设备可以被配置为实现用于将客户端设备连接到无线网络的至少两个虚拟接入点。 用户虚拟接入点使得客户端设备可以连接到无线网络，并将网络流量传输到连接到无线网络的其他设备。 此外，当用户改变用户虚拟接入点（例如服务集标识符（SSID）或密码）的网络凭证时，设置虚拟接入点提供附加接入点以连接到无线网络。 当客户端设备基于存储的SSID或密码找不到用户虚拟接入点时，可以将客户端设备配置为自动重新连接到安装虚拟接入点，以请求用户虚拟接入点的新SSID和网络凭证。
