  • Automatic test instrument for video generation and capture combined with real-time image redisplay methods
    Patent number: 8860759
    Abstract: Method of capturing multiple format video signals and reformatting them in real-time for display on generic external monitors, is disclosed. This method is intended for, by not limited to, implementation on a multiple function video test instrument with video generation and video capture capabilities. The method is capable of operating with standard and non-standard format synchronized video waveforms and also with deflection-driven video waveforms. Since this innovative method reuses already available functionality in the video test instrument, the new functionality is realized efficiently, economically and does not require any more space within the test instrument.

  • Heat exchanger
    Patent number: 4938284
    Abstract: A heat exchanger is provided in which two header tanks (11,12) are structurally connected together by two spaced apart casing members (15,16) therebeing a number of fluid conduits (13) to provide a fluid transfer connection therebetween. Each of the header tanks (11,12) includes a plate member (18) a side wall member (19) which defines in combination with the plate member (18) a fluid manifold each end of which is closed by a respective end cap (20A,20B,21A,21B). Each of the end caps (20A, 20B,21A,21B) includes means (25) used during assembly as an assembly aid. A further feature of the invention is the use of extruded material for several of the structural components.
