Abstract: Aspects of the invention include systems and methods configured to prevent masquerading service attacks. A non-limiting example computer-implemented method includes sending, from a first server in a cloud environment, a communication request comprising an application programming interface (API) key and a first server identifier to an identity and access management (IAM) server of the cloud environment. The API key can be uniquely assigned by the IAM server to a first component of the first server. The first server receives a credential that includes a token for the first component and sends the credential to a second server. The second server sends the credential, a second server identifier, and an identifier for a second component of the second server to the IAM server. The second server receives an acknowledgment from the IAM server and sends the acknowledgment to the first server.

Abstract: A tungsten-base alloy material and a preparation method therefor. The preparation method comprises: 1) evenly grinding composite powder containing tungsten and zirconium oxide, and then performing annealing treatment at 700-1000° C. to obtain powder A; and 2) grinding and then compression moulding the powder A, and then performing liquid-phase sintering to obtain a tungsten-base alloy blank so as to obtain the tungsten-base alloy material.

Abstract: An optical alignment device and method are disclosed. The optical alignment device includes an aligned light source, a carrying mechanism, a masking mechanism, and a transporting mechanism. The carrying mechanism is spaced apart from the aligned light source. The transporting mechanism is for driving the masking mechanism such that when the aligned light source is applied to the substrate carried by the carrying mechanism, the masking mechanism is controlled by the transporting mechanism to block a first area such that the optical alignment process is switched from the first area to a second area.

Abstract: A liquid crystal panel includes a plurality of main pixels, which may include main pixels having bright spot defects to be repaired. Each of the main pixels is of a charge-share pixel structure and the main pixel includes first and second voltage-division capacitors, which are connected in series. The first voltage-division capacitor includes first and second metal layers that are opposite to each other. The second voltage-division capacitor includes third and fourth metal layers that are opposite to each other. The first metal layer and the second metal layer of the first voltage-division capacitor of the main pixels to be repaired are additionally soldered together and the third metal layer and the fourth metal layer of the second voltage-division capacitor of the main pixels to be repaired are additionally soldered together thereby shorting the first and second voltage-division capacitors to achieve an effect of dark spot repair.

Abstract: The invention discloses a LCD panel including a display substrate. The display substrate includes a transparent substrate, pixel units, dummy pixel units, and a first wall. The transparent substrate includes a visual region, a dummy pixel setting region located outside the visible region, and a frame glue setting region located outside the dummy pixel setting region. The pixel units are disposed on the transparent substrate in the visual region. The dummy pixel units are disposed on the transparent substrate in the dummy pixel setting region. The first wall is set on the transparent substrate between the dummy pixel setting region and the frame glue setting region. The invention avoids the abnormal situation happening when coating the frame glue in the frame glue setting region, avoids the problems caused by the difficulty in controlling the accuracy of an alignment film, e.g. Mura, and improves the product yield.
