With a total of 16 patents to his name, Engdahl has made remarkable advancements that enhance the capabilities of solid-state radiation detectors.
Latest Patents
Engdahl's latest patents include innovative technologies such as the "Burst-mode readout for solid state radiation detectors using partitioned pipeline architecture." This invention introduces a partitioned pipeline read-out circuit architecture that eliminates real-time constraints from off-chip read-out control electronics in solid-state radiation detector systems. The design features a multi-channel ASIC with independently triggered charge sensitive pre-amplifiers, shaper circuits, and switched sample-and-hold capacitor circuits for each photodiode or pixel of the detector module. This allows individual photodiodes to detect and store scintillation events independently and randomly. Another notable patent is "Nuclear imaging using three-dimensional gamma particle interaction detection," which improves nuclear imaging by determining the depth of gamma ray/electron interaction within a semiconducting gamma ray detector. This method enhances spatial resolution, allowing for better imaging of positron-emitting objects.
