Vertical probe heads having a space transformer laterally tiled into several sections are provided. This change relative to conventional approaches improves manufacturing yield. These probe heads can include metal ground planes, and in embodiments where the ground planes are provided as separate metal plates parallel to the guide plates, the metal plates can also be laterally tiled into several sections. Such tiling of metal plates improves manufacturing yield and alleviates thermal mismatch issues. Probes are not mechanically connected to the space transformer, which facilitates replacement of individual probes of an array.

The present disclosure provides a slide gatefor use in conveyor systems that include permanent magnetsto hold slide gate components in place relative to a conveyor trough, while allowing the slide gateto slide between open and closed positions relative to an opening or cutoutformed in the conveyor floor. The slide gateis controllably opened and closed by an actuator system and can be magnetically attached to the actuator systemsuch that the slide gateis attached to the conveyor system entirely through magnetic force. Magnetic attachment of the slide gateprovides improved performance, ease of cleaning, and safety compared to known slide gate systems.
