Abstract
A mobile radiography apparatus includes a hybrid power supply system which includes batteries of different types. Each of the different type batteries is configured to supply electric power to a different portion of the mobile radiography apparatus. The different electric power supply characteristics of each the different battery types is matched to a corresponding power demand characteristic of one of the different portions of the mobile radiography apparatus.
Core Innovation
The invention relates to a mobile x-ray radiography apparatus and an x-ray apparatus that include an x-ray source and at least two different power sources or at least two different batteries. A first one of the power sources or a first battery is configured to provide power only for a first portion of the apparatus, while a second one of the power sources or a second battery is configured to provide power only for a second portion that does not include the first portion.
The moveable transport frame comprises a motorized drive control for moving the apparatus, and the first one of the power sources is configured to provide power for the motorized drive control. The architecture partitions power to different non-overlapping portions of the apparatus, matched to those portions’ power needs, and in the described embodiments the first portion includes the motorized drive control and the second portion includes an x-ray source.
A key aspect is that the first one of the power sources or the first battery is a non-lead-acid battery, including embodiments where the first battery is a lithium battery. The document also describes selective electrical connections between the power sources or batteries so that one power source can recharge the other, and example embodiments describe placement of different battery types in the transport frame, such as a battery powering wheel drive electronics and another battery powering the x-ray source.
Claims Coverage
The independent claims are clm-00001, clm-00008, and clm-00012. Across these independent claims, the inventive features focus on partitioned power to non-overlapping portions, integration with motorized drive control for a mobile apparatus, and the use of a non-lead-acid first power source or battery, with selective electrical connectability supporting recharging in dependent claim sets.
Partitioned power to non-overlapping portions
at least two different power sources, wherein a first one of the power sources is configured to provide power for a first portion of the mobile x-ray radiography apparatus and a second one of the power sources is configured to provide power for a second portion of the mobile x-ray radiography apparatus
Non-lead-acid power source powering motorized drive control
the moveable transport frame comprises a motorized drive control, and wherein the first one of the power sources is configured to provide power for the motorized drive control, and wherein the first one of the power sources is a non-lead-acid battery
Power partitioned between non-overlapping portions of an x-ray apparatus
at least two different power sources, wherein a first one of the power sources is configured to provide power only to a first portion of the apparatus and a second one of the power sources is configured to provide power only to a second portion of the apparatus that does not include the first portion of the apparatus
Motorized drive control in first portion powered by non-lead-acid battery
wherein the first portion of the apparatus includes a motorized drive control for moving the apparatus, and wherein the first one of the power sources is a non-lead-acid battery
Non-overlapping battery power portions for an x-ray apparatus
at least two different batteries, wherein a first battery is configured to provide power only to a first portion of the x-ray apparatus, and wherein a second battery is configured to provide power only to a second portion of the x-ray apparatus that does not include the first portion of the x-ray apparatus
Motor-driven wheels powered by non-lead-acid first battery
wherein the first portion of the x-ray apparatus includes electronically controlled motor driven wheels, and wherein the first battery is a non-lead-acid battery
Across independent claims, the document covers x-ray systems in which different power sources or batteries supply power to different non-overlapping portions of the apparatus, with the first portion containing motorized drive control or motor driven wheels and being powered by a non-lead-acid battery. The x-ray source is provided in a corresponding second portion in embodiments, and dependent claim sets further address selective electrical connection for recharging between the power sources or batteries.
