Abstract:
A touch panel and a display apparatus are provided. The touch panel includes a substrate, first sensing lines, second sensing lines, first extending portions, second extending portions, and insulation pads. The first sensing lines are disposed on the substrate in parallel with a first direction. The second sensing lines are disposed on the substrate in parallel with a second direction. The first sensing lines intersect the second sensing lines to define meshes. The first extending portions are connected to the first sensing lines and extended toward the meshes. The second extending portions are connected to the second sensing lines and extended toward the meshes. The first extending portions and the second extending portions are distributed next to each other in the meshes. The insulation pads are disposed at where the first sensing lines intersect the second sensing lines to insulate the first sensing lines from the second sensing lines.
Abstract:
A method, apparatus and database system restore tenant data in a multi-tenant environment. The method comprises: logging a plurality of tenants' requests to the database; with respect to a particular tenant who requires restoring tenant data, acquiring a log of events which affect contents of the database and start from a particular backup point; and only restoring in the database data of the particular tenant to the particular backup point, according to the acquired log of events. When a tenant performs a wrong operation on the database and wishes to roll back to a backup point, only information of the particular tenant in the database is changed into the information at the backup point, without affecting other tenants.

Abstract:
A perpendicular magnetic recording medium has an “exchange-spring” type magnetic recording layer (RL) with an improved coupling layer (CL). The RL includes the first or lower ferromagnetic layer MAG1, sometimes called the “media” layer, the second or upper ferromagnetic layer MAG2, sometimes called the “exchange-spring” layer, and the intermediate CL that provides ferromagnetic exchange coupling between MAG1 and MAG2. The CL is formed of NiCr or RuCr based alloys, or CoCr or CoCrB alloys with high Cr and/or B content (Cr plus B>about 25 atomic percent), or RuCoCr alloys with low Co content (
